FC4 kernels & Ingo Molnar's realtime-preemt patch?

[Patrick <fedora puzzled xs4all nl>]

Hi all,

Does anyone have any experience with applying Ingo Molnar's
realtime-preempt patch to recent FC4 kernels like 2.6.14-1.1633 in
Testing? I tried sticking patch-2.6.14-rt2 in the srpm's kernel-2.6.spec
as patch101 but that made patch810, patch812, patch1013, patch1083,
patch1500-1505 fail. So I commented them out. Then the build process
continued only to stop with make[1]: *** [nonint_oldconfig] Error 12
I really have no idea if this is possible at all or that I better should
use a plain vanilla kernel so any pointers appreciated.

The patch can be found at people.redhat.com/mingo/realtime-preempt/ 

Thanks and regards,
Patrick
