This patch, applied to 2.6.35-rc6, increases desktop interactivity
_NOTICEABLY_ on my quadcore machine, and the machine stays rock-stable.
I have now tested this patch with the latest 2.6.35-rc kernels over 
1 week.

Unfortunately, I can't provide some testing results which makes this
statement more objective, but I'll do some synthetic testing in the next
days.
