I was away until yesterday.. Don't know if this counts as proof or anything,
but with your patch, an ailing cyrix has been:

up    15:55,     0 users,  load 0.07, 0.08, 0.08

That includes one night => I presume it was idle enough for the change to
matter and your fix to kick in.

cpu0: family 6 model 0 step 0
cpu0: Cyrix 6x86MX (686-class)

I'll try to set up another one to improve the statistics a bit..

Thanks,
