I think the problem is in the swapconf() routine (rootfil.c) somewhere
near or at the call of the ???->p_size() routine. I ran into a similiar
problem when I tried to use a different root-device during startup.

I'm not sure if/how this is related to the new config, but eg. the new
SCSI sources have one of the size() routines reomved (I think sdsize()
is missing now). But I'm not sure about that, it's just an idea...
