I just tried booting off the FreeBSD 5.2 install disc on my system.  No 
crash on removal, but I do get the same three repeating error messages 
and still no device appears in /dev.  Then I tried this boot disc on an 
Intel (440BX) machine.  No error messages, but still no /dev entry.  I 
must be seeing both an old VIA-related 4.X bug and a newer 5.X bug where 
the device doesn't appear, which recently can also trigger a crash.

Did you say that you can mount the filesystem, and it freezes when you 
unmount it?  What happens if you just unplug the device after plugging 
it in?  I don't have a way to mount it, but unplugging the device 
crashes my system.
