Good news. The pcmcia patch I made for OSKit seems to work, of course
including some bugs. The patches for OSKit and gnumach are here [1].
I have two major problems found so far. First the hda geometry scan
will _only_ work if the console output goes over the serial line.
Booting without any attached null model cabel will result in
wrong hda geometry scan which prevents further booting. Unfortunately
I could not use gdb to debug because if gdb is attached I see a SIGTRAP in
copyout_retry().
While trying to isolate this trap, I found that this is triggered by
the first Load_context call. I guess that gdb points somehow after this call
on a page which not avaible anymore. This trap is always triggered
when I try to do remote debugging, even then when I set a breakpoint
with gdb_breakpoint in the source code after this Load_context
call. In short I can't use the debugger after this point. Therefore I
don't know how to haunt down the other bug.

Second problem is a panic, triggered by not very heavy lot on the net
device. A simple 'ls -lR' on a mounted nfs filesystem will caused
it. I haven't looked into that one yet.
