According to dmesg, the system finds the two cards:

[    6.044577] [drm] nouveau 0000:04:06.0: Detected an NV10 generation 
card (0x018500c1)
[    7.423750] [drm] nouveau 0000:04:06.0: Output VGA-1 is running on 
CRTC 0 using output A

[    7.432293] [drm] nouveau 0000:04:07.0: Detected an NV10 generation 
card (0x018500c1)
[56889.461496] [drm] nouveau 0000:04:06.0: Output VGA-1 is running on 
CRTC 0 using output A

But when I start X, I only get one display. I'm not sure what XrandR 
does exactly, but it seems to only report one card (run from within X):

westk@westek:~$ xrandr -q
Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 4096 x 4096
VGA-1 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 
338mm x 270mm
   1280x1024      60.0*+   75.0
   1152x864       75.0
   1024x768       75.1     60.0
   800x600        75.0     60.3
   640x480        75.0     60.0
   720x400        70.1
DVI-I-1 disconnected (normal left inverted right x axis y axis)
TV-1 disconnected (normal left inverted right x axis y axis)

The X log only seems to see one monitor:

(II) NOUVEAU driver for NVIDIA chipset families :
        RIVA TNT    (NV04)
        RIVA TNT2   (NV05)
        GeForce 256 (NV10)
        GeForce 2   (NV11, NV15)
        GeForce 4MX (NV17, NV18)
        GeForce 3   (NV20)
        GeForce 4Ti (NV25, NV28)
        GeForce FX  (NV3x)
        GeForce 6   (NV4x)
        GeForce 7   (G7x)
        GeForce 8   (G8x)

and as far as I can see it doesn't find the second monitor.

I remember reading somewhere that randr 1.2 doesn't support two video 
cards, but that 1.3 should:

(II) NOUVEAU(0): RandR 1.2 enabled, ignore the following RandR disabled 
message.
(--) RandR disabled

but
westk@westek:~$ xrandr -v
xrandr program version       1.3.2
Server reports RandR version 1.3

I don't know if I'm using randr 1.2 or 1.3, or even it that's apropos to 
my lack of dual-monitors.
