OK here's the answer to XP pokey mouse with credit for its development and
inspiration To *RHH* at *codecpage.com*:

With the information and links to information from the codecpage.com website
and use/tweaking of RHH's spreadsheet (which allowed me to understand how to
read and write the registry entries in Hex and convert back and forth from Hex
to Decimal) I have completed some testing of various mouse settings.

My testing confirms that it isn't necessary to modify the smoothXcurve registry
entry from their defaults.  Speed up of the mouse is obtained merely by
adjusting the smoothYcurve line only.  This can be tested by setting the
smoothXcurve registry entry to be the same as the smoothYcurve registry entry. 
The smoothYcurve default entry contains more and faster acceleration than the
smoothXcurve.  Originally I would have expected the substitution of the
smoothYcurve values for the smoothXcurve values to therefore result in some
amount of speed up of the mouse.  Instead what I got was a much *slower* mouse.
 This confirmed that the X values and Y values aren't working the way we would
normally expect.  It could be that the X line is the minimum acceleration and
the Y curve is the maximum acceleration, as opposed to corresponding to the X
and Y planes that the mouse physically moves through (as one would ordinarily
think).

Anyway, armed with this understanding I took the RHH spreadsheet and after
making a few personal tweaks to the spreadsheet began testing various
configurations for a speedier mouse.  I kept the X curve values at their
default settings and merely tested changes to the Y curve values.  After many
hours of testing over two different days, I came up with the following settings
that work very smoothly and fast for my particular hardware (a synaptics
touchpad and external PS/2 optical desk mouse; both controlled by the latest
synaptics software drivers).

*Here are the registry modifications* (See attached txt file and rename its
extension to .reg):

REGEDIT4

[HKEY_CURRENT_USER\Control Panel\Mouse]
"SmoothMouseXCurve"=hex:00,00,00,00,00,00,00,00,15,6e,00,00,00,00,00,00,00,40,\
01,00,00,00,00,00,29,dc,03,00,00,00,00,00,00,00,28,00,00,00,00,00
"SmoothMouseYCurve"=hex:8f,52,00,00,00,00,00,00,ce,9c,01,00,00,00,00,00,00,80,\
11,00,00,00,00,00,34,33,4d,00,00,00,00,00,00,00,30,07,00,00,00,00


I also use the following additional registry entries regarding mouse speed:

REGEDIT4

[HKEY_CURRENT_USER\Control Panel\Mouse] "MouseSensitivity"="18"
"MouseSpeed"="2"
"MouseThreshold1"="6"
"MouseThreshold2"="12"


The MouseSensitivity line is the value set as determined by the speed slider
bar on the mouse control panel applet.  a value of 20 is its max speed setting
and the value 18 is the next to the highest speed setting on my synaptics
touchpad driver controlled mouse applet.

I use these settings with my PS/2 attached logitech/MS compatible desktop
optical mouse.

%I also set the PS/2 refresh rate to its maximum of 200 reports per second
and the buffer size to its maximum of 300.  These settings are found on the
mouse properties page under device manager.%

*I followed this procedure:* Modify the XY curve and other registry entries,
and then using the mouse control panel applet to adjust the slider bar and
apply settings ( then I would move the slider bar back to where I had it
originally/wanted and then apply settings again).   This was to try and get
the drivers to re-establish the acceleration tables based upon the modified XY
curve registry entries.  Then I re-applied the registry changes (because some
of the entries will get changed back to their defaults when using the control
panel mouse applet) and then rebooted.  *You must reboot for the changes to
take effect.*

If my bios has such a setting I'm not allowed to see it.  I can't see or tweak
most bios settings on my gateway laptop.

Let me know if you like the effects of the above.
