Hm, I couldn't reproduce the panic after setting "dumpdev" correctly in 
loader.conf (it refered to a non existing partition). I also used
hw.physmem="2G" (instead of the 3G of memory).

I try again without the hw.physmem setting and see if I can reproduce 
it. Or could it be related to maybe dumpdev (or the missing swap partition)?
