It seems my comment was a bit misleading: it's not only that we don't use
the CVS anymore, the source code base in the CVS is also older (and
different) compared to the code base in the now-referenced HG repo.

OK. I don't know of anybody in our group using anything else than serial
ports 
for console I/O for development, so the VGA could very well be the problem. 
The repo currently works with VGA and qemu on my box, though. So you could
try 
building for the qemu emulator yourself, and start from there. Just check
out 
the HG repo, build the everything using the default config, and then run
"make 
run-qemu". That should bring up the afterburner qemu.

If you then still get problems on a real box, you'll have to find the
culprit 
for the null pointer dereference. I'd suggest to inspect wedge and linux
stack 
contents to get a feeling where the problem stems from.
