So, I guess we won't have the option to choose between different CPU
schedulers (desktop or server, for example), like we have in -mm kernels
with IO schedulers (deadline or anticipatory).

Seriously talking, I prefer to have the best performance in my server
boxes, but for my laptop, I prefer shorter timeslices, lower peformance
and better turnaround times and a wiser CPU scheduler. Just my two
cents.

It's sad to say but I feel the vanilla 2.5 CPU scheduler doesn't match
my end-user preferences :-(
