Sadly I get the same panic when I do that on my hardware.  Equally sadly 
I'm no kernel programmer so my attempt to chase down the panic by 
looking at the current rev of kern_mutex.c didn't yield anything.  A 
pity because I'd like to get FreeBSD working on this machine and then 
see if any userland needs tweaking (my C skills do at least run that 
far) - so if there's any way I can help track down this problem I'd like 
to do that.  For instance:

Actually, I probably *could* create a bootp environment so that the 
Sawtooth boots the kernel over the network then tries to use the 
filesystem on the CD as its root, would that work?  Could I use that to 
attack the kernel problem?  How would I build the FreeBSD kernel under 
Darwin?
