Hi list,
my thanks to developers of nouveau first: I wonder how you put it together this 
far, where there's quite enough to appreciate!

This question I have: strangely I can get each of 2 cards to work separately 
for a dualseat PC by toggling on/off fbcon=map: kernel option (compiled with 
CONFIG_FRAMEBUFFER_CONSOLE_DETECT_PRIMARY) -- by doing so I can have each card 
initialized and start it's Xorg, all welll, but can't have both cards 
initialized (and thus used) -- why?

In very short, this is what my dmesg says:
[drm] Initialized drm 1.1.0 20060810
nouveau 0000:01:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
[drm] Initialized nouveau 0.0.16 20090420 for 0000:01:00.0 on minor 0
nouveau 0000:04:00.0: enabling device (0000 -> 0002)
nouveau 0000:04:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
nouveau 0000:04:00.0: PCI INT A disabled
nouveau: probe of 0000:04:00.0 failed with error -12

0000:01 is address of one card, 0000:04 of the other. What happens is that one 
of cards will fail to be initialized (in one case 01, other time 04). So is 
that supposed to be that way currently or I missed to pass some parameters or 
bug, or..? What more should I post here if anyone interested in this?
