no direct rendering with 2.6.26 due to AGP after DRM

no direct rendering with 2.6.26 due to AGP after DRM

Hi,

with 2.6.26, I got no direct OpenGL rendering in Xorg. A look into the
dmesg lock revealed this:

2.6.26:

[drm] Initialized drm 1.1.0 20060810
ACPI: PCI Interrupt 0000:00:02.0[A] -> GSI 16 (level, low) -> IRQ 16
PCI: Setting latency timer of device 0000:00:02.0 to 64
[drm:drm_fill_in_dev] *ERROR* Cannot initialize the agpgart module.
DRM: Fill_in_dev failed.
...
agpgart: Detected an Intel 965GM Chipset.
agpgart: Detected 7676K stolen memory.
agpgart: AGP aperture is 256M @ 0xe0000000

2.6.25.9:

Linux agpgart interface v0.103
agpgart: Detected an Intel 965GM Chipset.
agpgart: Detected 7676K stolen memory.
agpgart: AGP aperture is 256M @ 0xe0000000
[drm] Initialized drm 1.1.0 20060810
ACPI: PCI Interrupt 0000:00:02.0[A] -> GSI 16 (level, low) -> IRQ 16
PCI: Setting latency timer of device 0000:00:02.0 to 64
[drm] Initialized i915 1.6.0 20060119 on minor 0

Any hints what I could try to solve this?

For now don't built it all into the kernel :)

I'll see what I can dig up on init ordering.

My bad. I didn't use 2.6.26, but some git version after 2.6.26. Another
computer with a real 2.6.26 was fine, so scratch all of the above.

Yes its not in real 2.6.26 but I have a patch now, to move gpu after char 
in the Makefile..
