AGP is an extension to the PCI specification.
Therefore you get even AGP slots listed when running "lspci".
I know that PCI:1.0.0 is working on specific machines
and it nicely selects the AGP board. I have never seen
that you can replace "PCI" by "AGP". Maybe it just works
because your AGP display adapter is setup as the only
remainder and therefore your section just applys.
I would suggest you to test those two boards separately,
even with only one plugged, in order to find a working
single screen setup. increase complexity step by step:
- running each board with only one board plugged
- running each board single head with tow boards plugged
- running true dual head
else you will get too manu uncertainties into your setup.
If you find something to be instable, then retest your
hardware with an alternate OS that does drive multihead
as well. In several cases you will spot hardware lacks,
like poer supply or mainboard power transmission shortage
plus any sort of bus incompatibility or signal weakness.
