[Intel-gfx] i915 module does not find 82865G if configured as secondary

[Tempura San]

Hi everybody,

I want to set up the following configuration:

Primary display:
00:02.0 Display controller: Intel Corporation 82865G Integrated Graphics
Controller (rev 02)

Secondary display:
03:0a.0 VGA compatible controller: Avance Logic Inc. ALG-2302

The 82865G is onboard, but via BIOS the other (PCI) card is activated.
In the end I would like to run Xorg on the 82865G card and keep the
console output on the PCI card.

But Xorg is not able to locate the card. I (think I) tracked the problem
down to the i915 module as it is not finding the card if it is not the
active one and the Xorg module relies on the DRM driver.

82865G as primary:
[drm] Initialized drm 1.1.0 20060810
[drm] set up 31M of stolen space
[drm] initialized overlay support
fb0: inteldrmfb frame buffer device
[drm] Initialized i915 1.6.0 20080730 for 0000:00:02.0 on minor 0

82865G as secondary:
[drm] Initialized drm 1.1.0 20060810

...and nothing else.

With lspci -v the 82865G (as secondary) is listed like:

00:02.0 Display controller: Intel Corporation 82865G Integrated Graphics
Controller (rev 02)
	Subsystem: IBM Device 0285
	Flags: fast devsel, IRQ 11
	Memory at d8000000 (32-bit, prefetchable) [disabled] [size=128M]
	Memory at d0080000 (32-bit, non-prefetchable) [disabled] [size=512K]
	I/O ports at 1890 [disabled] [size=8]
	Capabilities: [d0] Power Management version 1

I tried to enable the card by doing
# echo 1 > /sys/bus/pci/devices/0000\:00\:02.0/enable

In dmesg the following lines are printed:
...
pci 0000:00:02.0: enabling device (0000 -> 0003)
pci 0000:00:02.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16

But even after rmmod'ing the kernel modules nothing is printed except:
[drm] Module unloaded
[drm] Initialized drm 1.1.0 20060810

I am running the current stock Debian Squeeze (kernel 2.6.32-5-686).

So my question is: why is the card not recognised? Am I missing something?

Maybe the configuration I want to run is not possible?

Any help would be great!

Thank you & Cheers,
Tempura
