I assumed that Gimpel did not apply core patches because he had compiling error:
fs/built-in.o(.text+0x92999): In function `reiser4_put_super': undefined reference to `rcu_barrier'.

However, the problem is that some changes are to be done to get reiser4 to work in new realtime/preempt kernels.

You go right way.

reiser4-for-2.6 contains code which did not get enough stability yet.
