Nouveau - Apr 2008 - "Unknown LVDS configuration bits, please report" - Error

Hi,
I tried to run nouveau under Ubuntu 8.04, it failed with the error
mentioned in the subject.

The graphics card in question is:
01:00.0 VGA compatible controller: nVidia Corporation Quadro NVS 135M
(rev a1)

Some X specific output:
X.Org X Server 1.4.0.90

I have the Xorg.0.conf copied and can send it, as it has around 90k I do
not really want to send it to the mailing list. The lines with warnings
or errors are:

"Framebuffer loaded" is usually a bad sign. The Nouveau driver does
not
work reliably with a framebuffer driver loaded. Granted, there are rumours
that vesafb should work, and that on PPC you have to use the... hm, I fail
to recall the driver name, offb? Anyway, in the future it is preferred to
not use any framebuffer drivers, if possible. Nvidiafb will surely cause
pain.

But, I don't think this is an answer to your problem, this is just a
sidenote.

To my unexperienced eyes, this looks just a not-fully-supported hardware.
Have you searched the bugzilla? I guess there might already be a report
for this specific case. If not, please add a bug, so the developers can
track it.
