I suspected the video card was the problem but haven't had a chance
to set up a serial port connection to try it out.

ofb0 at pci0 dev 16 function 0: ATI Technologies Rage Fury MAXX AGP 4x (TMDS)
ofb0: 640 x 480, 8bpp
wsdisplay0 at ofb0 kbdmux 1: console (std, vt100 emulation)
wsmux1: connecting to wsdisplay0

It also has the mmap screen problem with X that others have mentioned :

(II) Setting vga for screen 0.
(II) Loading sub module "vbe"
(II) LoadModule: "vbe"
(II) Loading /usr/X11R6/lib/modules/libvbe.a

        compiled for 4.4.0, module version = 1.1.0

Fatal server error:
