Panic/Fatal trap 12 while installing 6.1-RELEASE

[Juha Saarinen]

Trying to install 6.1 on a Gigabyte 8i955 Royale motherboard, with an
Intel D840 and 2GB of RAM onboard. However, booting up from the 6.1 CD
results in a locked up system and this on the screen:

Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x4
fault code = supervisor write, page not present
instruction pointer = 0x20:0xc07b5e7d
stack pointer = 0x28:0xc1020d44
frame pointer = 0x28:0xc1020d58
code segment = base 0x0, limit 0xfffff, type 0x1b
                     = DPL 0, pres 1, def 32 1, gran 1
processor eflags = interrupt enabled, resume IOPL = 0
current process = 0 ()
trap number = 12
panic: page fault
uptime: 1s

Not sure where to go from here, as system locks up solid. Booting with
ACPI disabled and Safe Mode result in:

vm_page_insert: page already inserted

and system lockup.

Verbose logging, and I get the exact same Fatal trap 12 as above.
