Actually, sorry, it's already merged -

http://www.kernel.org/git/gitweb.cgi?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=976ecd12b8144d066a23fe97c6fbfc1ac8470af7

I don't personally run preempt so I don't know what badness you're
seeing.  Can you check whether your kernel has this patch applied,
and if so provide a bug report so the problem can be analysed please?
