I'm 98% ignorant here, but if I disable my cache, I get much decreased
Bogomips... I assume that Bogomips specifically will only show a difference
unless a few K is installed and be exactly the same above that level.

I would say: try using time and some math-intesive toy like gcc or povray
and time it several times. If you can disable it in CMOS/BIOS and get no
worse results you probably have been taken. (of course run 3 or 4 trials to
counter the disk-buffering etc.

(Am I speaking completely out my arse here?)
