This is a module stacking issue. Those are defined in ksyscall.o.

Ditto... bproc.o (I think) This time.

Ditto... ksyscall.o and bproc.

The first cut of BProc split things up a little more. The 2.x revs of
BProc have ghosts on the slave side as well so the ghost and masq
pieces were combined into one module. 3.x will make the dividing line
between these functions clearer again but it will probably still be a
single module since it's just not that big. There were was no 1.x
version BProc. (Don really wanted it to be bproc 2 to coincide with
beowulf 2 so I humored him.)

Besides working on newer kernels, the newer ones are quite a bit less
broken. If you want to just try it quickly, you can get pre-packaged
kernel and bproc RPMs from Scyld's ftp site. Those will drop in on
top of Red Hat 6.2 very cleanly.
