Kernel Panic on boot

["Eric J. Christeson" <ejc@xxxxxxxxxxxx>]

I've got a laptop here that I'd like to get DragonFly running on.  The
problem I'm running up against is a kernel panic on boot.  I'm using the
2004-01-18 CD.  It has a similar, if not same, panic on FreeBSD 4.9 and
5.2.1 so it's probably rouge hardware.  DragonFly is the only one of the
three that seems to have a debugger built in to the kernel and it's my
preferred OS.
Attached is a verbose boot.

Thanks
eric
