I have a netbsd/amd64 machine with several vga cards (e.g., 2x Nvidia
GeForce 7900 GTX (2 ports each), 1x Matrix G200 (4 ports)).  See the
dmesg output below.  I am trying to get these all to work with X.
Several issues arise.

First, I cannot seem to get the kernel to install different vga
devices for the cards.  Is it possible to have multiple vga devices?

Second, should X see each port for the 7900 cards as a distinct
device?  (All 4 G200 ports can be made to work independently.)  If so,
how are they addressed within the X config file?  Is it possible that
the cards require some sort of kernel setup in order to make them
detectable by X?

Finally, with certain X configurations it seems that both 7900 cards
are detected.  However, X apparently sees the second one at a pci
address of 129:0:0 not at 7:0:0 as I would expect from the kernel.
(One port on the first card at 2:0:0 can be made to work or both ports
on that card can be forced side-by-side using the DualHead hack.)
Furthermore, X reports that the second card (129:0:0) has no memory.
Does this mean that there are colliding pci resource issues?

If anyone has experience with multiple vga cards and X, I would
appreciate some assistance.

Thanks *alot* for your help.

Cheers,
Brook
