Hey James!

Some interesting stats for linux-2.6.27.8 Note just under two minutes to build
a kernel from scratch.

From a cut and paste 'cat /proc/cpuinfo';

Also FYI;

The onboard ethernet is using the e1000e and;

root [ ~ ]# find /proc/ -name eth0
/proc/irq/381/eth0
/proc/sys/net/ipv4/neigh/eth0
/proc/sys/net/ipv4/conf/eth0

Everything works as advertised.

So it is possible to make a kernel, with modules, in ~3 minutes.  That is
faster than it took me to create a .config!!!  I think this machine is a
keeper.

Life is good,
Maurice
