X log

X does not start.

I am running 
linux 2.6.33, 
libdrm 2.4.18 
nouveau git
X 1.7.5
Mesa 7.7

It opens the drm device and then says it failed to open it.

I suspect I have kernel module 0.0.15 and libdrm module 0.0.16 but it is not
mentioned anywhere in the log that the versions do not match.

drm dmesg excerpt

Installing the firmware changes dmesg output slightly but the X server fails in
the same way producing the same log.

Update to lastest git, there is no need to install firmware (nouveau tree or
kernel 2.6.34-rc1+).

With 2.6.34-rc1 the X server starts.
The kernel also says in the log that it has version 0.0.16 of the nouveau drm
module.

Is it possible that when the kernel drm version does not match the driver
version it just quietly exits instead of reporting a meaningful error?

Closing this since the issue is fixed.

And no nouveau doesn't silently fails, it always prints "(EE) [drm]
failed to
open device".

That's not exactly helpful output as that same message is output on various
occasions and does not point at the actual issue at hand.
