Yeah their product numbers are not really the clock speed.  My
understanding is they were saying  an Athlon 2800 was clocked slower
but still about as fast as an Intel at 2800... but that might just be
my own bad memory.

Starting timesync from the live cd does cause a lot of interrupts yes.
 But my network wasn't configured either, which is seemingly the same
thing going on with my plan 9 installation since I didn't configure
any network.

perhaps timesync should not be on in the default installed
distribution, and users should turn that on themselves once they have
their network configured properly?
