There's a dmesg and pciconf at
http://stuff.mit.edu/afs/sipb.mit.edu/user/kaduk/freebsd/periphrasis/

The motherboard is a Gigabyte GA-P35-DS3L, so Intel P35 northbridge
and Intel ICH9 southbridge; the actual video card came with very
little documentation, but purpots to be a Radeon B2 256 HD2400PRO PCIe
by VisionTek.  The HD2400Pro part certainly seems accurate, at least.

When setting up radeonhd for the card, I did need to toggle the hotplug
detection bit in xorg.conf to get dual-monitor support; I haven't updated
xorg since I filed that report, so I don't know if's been fixed already.
