Assuming this is an i386 kernel, in the timeofday patches, the __delay
function has been converted to be a simple loop based delay instead of
TSC based, since the TSC has too many potential problems.

That should explain a differing lpj value, although 10x smaller is a
little strange, so I'll dig into this on my system and see if I find
anything.

Do let me know if you see any actual changes in behavior (drivers acting
funny, etc).

thanks
