How recent a Reiser4 do you need?  There are some patches against the 
vanilla kernel at

http://namesys.com/pub/reiser4-for-2.6/

But those seem out of date and don't work for me.  But, the patches from 
the mm-kernel have been rock-solid for me.  I'm taking the vanilla 
2.6.12.3 kernel and patching it with the Reiser4 patches from 
2.6.12-mm2.  Unpack this:

http://kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.12/2.6.12-mm2/2.6.12-mm2-broken-out.tar.bz2

to /usr/src/ and run this:

#!/bin/sh
# hack to bring mm reiser4 back to vanilla
cd /usr/src/linux
for i in `grep reiser4 ../broken-out/series`; do
	patch -p1 < ../broken-out/$i;
done

I've attached one patch of my own that makes it compile properly -- 
apply after you run the script above.
