Yes. I had applied the preempt patch to a pre-10 along with the xfs
patch. I remember an additional patch was required to build but it was a
simple include directive change, so I'm not sure if I used that minor
patch or corrected it myself. Since then 2.4.10 came out and patches
exist for it. Here's what to grab:

http://www.tech9.net/rml/linux/preempt-kernel-rml-2.4.10-6.patch
(see also: http://www.tech9.net/rml/linux/)

ftp://oss.sgi.com/projects/xfs/download/patches/linux-2.4.10-xfs-2001-10-03.patch.bz2
(see also: http://oss.sgi.com/projects/xfs/faq.html#xfspatches)

and of course,
http://www.kernel.org/pub/linux/kernel/v2.4/linux-2.4.10.tar.gz

Unpack linux-2.4.10.tar.gz into some dir (not /usr/src unless you move
the existing linux/ out of the way) then move the unpacked linux-2.4.10
dir across to /usr/src/linux-2.4.10 and symlink linux-2.4 (and maybe
also linux) to linux-2.4.10. Then "cd /usr/src/linux" (you should be in
/usr/src/linux-2.4.10 at this point). Well, you know what I mean...

Then patch:

bzcat /path/to/the/linux-2.4.10-xfs-2001-10-03.patch.bz2 |patch -p0
patch -p0 </path/to/the/preempt-kernel-rml-2.4.10-6.patch

The patches should apply cleanly.

Then "make mrproper", play with your default configs, then "make
xconfig", "make clean", "make deps", "make bzImage" and then play with
lilo.conf.

I hope a preemptable kernel comes to a redhat distro soon.
