Sounds like it :)  Don't know it if works, though, can anyone test?  (note 
that it's there in all kernels...)

I've not attempted mozilla (I've the source around here somewhere...)  as 
I've not done a recent world, so I've not got the ld.so tweak needed for it.

I have found something scary in the cpuswitch.S, and that's that it uses ffs 
to find the first queue with work, so for the most part if there's only user 
process running it was looping 12 time (eeks the pipeline!!!)  to find the 
running process that's at the head, I know not a major thing, but I suspect 
that cpu_switch is hit regularly?  Anyway I'm compiling up a kernel with this 
tweaked (I finnally got around to digging out the ffs stuff of the mailing 
list from 2 years back, the ffs version that's fixed time, does a mystical 
multiply and then lookup from table.)

Anyway once it's working it'll eventually make it into the tree I hope :)
