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
Release Date: 5 September 2007
X Protocol Version 11, Revision 0

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:
