*grin*  Don't expect fast responses from me -- I've got a real life, and a
show in Birmingham to prepare for...

Be careful: the UBC integration broke things rather.  You'll need
sys/arch/arm26/include/vmparam.h to be at least revision 1.2 to get beyond
the copyright notice.

I don't know.  I don't think I've ever seen that panic happen before.

Do you know if it's started init by then?  If you haven't got DDB built in
to the kernel, build it in, then you'll get dropped into it at startup and
can type "t" to get a stack backtrace (and "ps" to get a process listing).  
I think it should correctly trace back through the trap.

Those won't be touched for a while -- you need to get syslogd running
first.
