Trivial cosmetic tweak to make the i[56]86 CPU MHz reprting round to the

Browse Source 
nearest .01 Mhz rather than simply truncating it downwards.

This hack makes this 89.999928 Mhz clock correctly round to the closer
90.00-MHz rather than 89.99-MHz:
  > i586 clock: 89999928 Hz, i8254 clock: 1193152 Hz
  > CPU: Pentium (90.00-MHz 586-class CPU)
