nouveau: [drm] failed to open device

[Daniel Mack <daniel-rDUAYElUppE@public.gmane.org>]

Hi,

I'm trying to get the new nouveau kernel driver (2.6.33-rc8) to work
with X.Org 1.7.4 (Debian/unstable, all relevant packages updated). The
modules load just fine, and the kernel spits out the following upon
probe:

[    8.304602] nouveau 0000:06:00.0: PCI INT A -> Link[LNEB] -> GSI 18 (level, low) -> IRQ 18
[    8.304779] nouveau 0000:06:00.0: setting latency timer to 64
[    8.313364] [drm] nouveau 0000:06:00.0: Detected an NV40 generation card (0x044300a2)
[    8.313812] [drm] nouveau 0000:06:00.0: Attempting to load BIOS image from PROM
[    8.521142] [drm] nouveau 0000:06:00.0: ... appears to be valid
[    8.521148] [drm] nouveau 0000:06:00.0: BIT BIOS found
[    8.521151] [drm] nouveau 0000:06:00.0: Bios version 05.44.02.62
[    8.521156] [drm] nouveau 0000:06:00.0: BIT table 'd' not found
[    8.521159] [drm] nouveau 0000:06:00.0: Found Display Configuration Block version 3.0
...


However, when starting X.Org (installed from the Debian package), I get
this:

From the strace output (http://pastebin.com/m12d5b19a) I cannot see what
the problem could possibly be, and searching the FAQs and archives
didn't help me either. I can't see any errors or warning anywhere
except for the one above.

The full X log is here: http://pastebin.com/m731c3561
And my xorg.conf is here: http://pastebin.com/m5f143408

Any pointers appreciated - I got the evil feeling to overlook the
obvious ;)
