Do you have any indication how far it comes? Do you have kgdb
working, or a good BDM debugger (i. e. one with MMU support)?

It depends on what you mean with 2.3; it's just two days that I have
2.4.0-test5 running stable on TQM8xxL boards. This is the _first_
kernel after 2.3.18 that ever ran for me on a MPC8xx. And even this
is only when you fix cache problems in string.S (either by simply
replacing the file with the version from 2.2.13, or by applying Dan's
patch).
Sorry, I don't have any RPX boards here to test, but I have tested
three systems (2 x 850 and a 860), two of them under > 24 h stress
tests (with things like compiling the linux kernel on the target),
and I had not a single problem since.
In case you're interested - I've put my patches against the
2.4.0-test5 BitKeeper sources on our FTP server (the "COMMON" patch
includes all I neded to change for TQM8xxL support to the current
kernel; the "TQM" patch is probably of little interest since this is
just needed when you use the old TQ monitor instead of PPCBOOT):
ftp://ftp.denx.de/pub/LinuxPPC/usr/src/patches/COMMON-2.4.0-test5.patch.gz
ftp://ftp.denx.de/pub/LinuxPPC/usr/src/patches/TQM-2.4.0-test5.patch.gz

Real programmers don't comment their code. It was hard to write, it
should be hard to understand.
