Died in the BIOS.  5.x definitely has grown some kind of bug for the
bios32() stuff.  I get this type of panic on Intel 845 adn 865 motherboards
if ACPI is disabled when the kernel tries to enumerate PnPBIOS devices.
Using an install CD which has a full kernel and includes acpi.ko might
work.  Alternatively, you could try using FreeBSD 5.2/amd64 to run FreeBSD
as a native 64-bit OS.
