Well, the bogomips are less, and its a Old Tbird, so no sse. But it has a much 
larger cache... That could make a difference.

processor       : 0
vendor_id       : AuthenticAMD
cpu family      : 6
model           : 4
model name      : AMD Athlon(tm) processor

cpu MHz         : 899.674
cache size      : 256 KB

hlt_bug         : no

coma_bug        : no

Depends on how much the bogomips actually corresponds to something like a long 
compile... ohh, its also a 100mhz buss, so I'll bet the Nemiah will at least 
keep pace with it, if not be a bit faster. (My new XP 2400+ will likely kick 
its bacon though) ohh. wait, I remember hearing about issues with the Nemiah 
not supporting some of the optional instructions.. I'll have to read the 
howto again :D
