Some apps that want a Pseudocolor visual can find one.
Others are brain-dead and assume that the default visual is Pseudocolor.
If we make Pseudocolor the default (as we did with 8+24/overlay on
Matrox cards last time I looked) then some lazy apps take the default
and use up all the available colours, even when they could use a
better visual and avoid wasting colours :-(

"xv -visual pseudocolor filename" works on my Millennium.
You need to include
Option "Overlay"
in the device section of the config file.

As Mark said, this doesn't need two cards or monitors
(at least on OSes with virtual terminals - Linux is fine).
It is your simplest option, and is likely to work.
However the README for at least one driver claims this is "unsupported".
