I use the kernel patch as I tune my kernel to suit my clusters hardware.

If you have the rpm kernel working, then that should not really be a problem
as distcc only sits infront of your compiler (mine is configured using:
PATH="/usr/lib/distcc/bin:${PATH}"
and the appropriate symbolic links set in /usr/lib/distcc/bin as follows:
# ls -l /usr/lib/distcc/bin/
total 0
lrwxrwxrwx  1 root root 15 Dec 14 22:54 c++ -> /usr/bin/distcc
lrwxrwxrwx  1 root root 15 Dec 14 22:54 cc -> /usr/bin/distcc
lrwxrwxrwx  1 root root 15 Dec 14 22:54 g++ -> /usr/bin/distcc
lrwxrwxrwx  1 root root 15 Dec 14 22:54 gcc -> /usr/bin/distcc
lrwxrwxrwx  1 root root 15 Dec 14 22:54 i386-pc-linux-gnu-c++ ->
/usr/bin/distcc
lrwxrwxrwx  1 root root 15 Dec 14 22:54 i386-pc-linux-gnu-g++ ->
/usr/bin/distcc
lrwxrwxrwx  1 root root 15 Dec 14 22:54 i386-pc-linux-gnu-gcc ->
/usr/bin/distcc

These represent the compilers that exist in /usr/bin on every node (there
are more ways of using distcc but this is how it works on my nodes)

Basically, if your kernel is working and you can compile without distcc,
then distcc will work.
(aslong as all nodes running distcc use the same compiler tools and know
where the other nodes exist on the network)

Not sure if this helps, but its possible that if everything works untill you
use distcc, then it could be that not all nodes have the same compiler tools
(All my nodes use the same kernel, distro and compiler tools on their own
roots)
