I did a quick try of this script here.

With SD 0.46 with X at nice 0 I was getting 1-2 frames per second.  I decided to try cfs v5.
The option disable auto renicing did not work so many threads other than X are now at -19...

SD 0.46		1-2 FPS
cfs v5 nice -19	219-233 FPS
cfs v5 nice 0 	1000-1996

Looks like, in this case, nice -19 for X is NOT a good idea.

Kernel is 2.6.20.7 (gentoo) UP amd64 with HZ 300 voluntary prempt (a fully premptable kernel eventually 
locks up switching between 32 and 64 apps)

Thanks,

Ed Tomlinson
