Hello Maurice!

 For the RaspberryPi 700Mhz is the default. Above that speed it is considered
 overclocking. The speed is set in a configuration file. More heath is
 generated at higher speeds and possibly you will have to increase the
 voltage. With no forced cooling, you may have to add some. I run mine
 at 800Mhz.

$ cat /proc/cpuinfo
processor   : 0
model name  : ARMv6-compatible processor rev 7 (v6l)
Features    : swp half thumb fastmult vfp edsp java tls
CPU implementer : 0x41
CPU architecture: 7
CPU variant : 0x0
CPU part    : 0xb76
CPU revision    : 7

Hardware    : BCM2708
Revision    : 000d
Serial      : 00000000********

I removed the serial number.

 $ cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq
800000

 So it is the speed I set in the config file.

 The arm version gives neither, maybe sometime in the future.
