Dual-headed X setup?

[Datawolf]

>From the XFree86 FAQ <http://www.xfree.org/FAQ/>:

"Q.A15- Can I use more than one video card in the same machine with
XFree86?

"Although it is technically possible to use multiple PCI-based SVGA
cards in the same machine, none of the servers currently support this.
The VGA16 and Mono servers are both capable of running both a VGA
compatible card and a non-VGA compatible monochrome card in the same
machine. For XFree86-4.0 we are working on true multi head support."

>From the XFree86 4.0 Release Notes
<http://www.xfree.org/4.0/RELNOTES2.html#7>:

"2.5. Multi-head

"Some multi-head configurations are supported in this release, primarily
with multiple PCI/AGP cards. However, this is an area that is still
being worked on, and we expect that the range of configurations for
which it works well will increase in future releases. A configuration
that is known to work well in most cases is multiple (supported) Matrox
cards.

"One of the main problems is with drivers not sufficiently initialising
cards that were not initialised at boot time. This has been improved
somewhat with the INT10 support that is used by most drivers (which
allows secondary card to be "soft-booted", but in some cases there are
other issues that still need to be resolved. Some combinations can be
made to work better by changing which card is the primary card (either
by using a different PCI slot, or by changing the system BIOS's
preference for the primary card)."
