Heh, MDA has been described in the kernel source as 'pre-dinosaur hardware'. 
Its basically a monochrome text-only 9-pin display output. In kernels 2.0 it
played with other video cards happily, but since 2.4 its gone a little
wonky. I'm still trying to figure out where in the source the issue is.

i think you're going to be stuck with one video card then.

Actually, yes you can, if you run 'lspci' with no options, each item
connected to the machine will produce a type of 'address' .. typically like
00:00.0 format. An item that starts with 00 is PCI, if it starts with 01
is AGP.

I remember a while ago reading some article about a company creating a
PCI style video card but with a 9 pin RS-232 serial output on the other
side. Neat idea to create a headless machine... Basically you could monitor
everything including the bios via a serial port.
