I with 2.6.10 a problem came up that had me looking into this too.

Using gcc 3.3.3, my xfree86 is built from cvs release xf-4_4-branch.
When I tried 2.6.10, it built with no problems.

To the best of my knolege, xfree86 is not including any kernel
headers, my source is not where any package would know to look and
there don't seem to be any distro (woody) kernel header packages
installed. I could be wrong, but I don't know where they might be
found, or that I ever needed them for this xfree86 build.

The problem is running X, my display is littered with flashing bits,
as if the card is rendering some cpu register or bus in 2% of the
display.

02:00.0 VGA compatible controller: nVidia Corporation: Unknown device

Expansion ROM at <unassigned> [disabled] [size=128K]

Is this due to namespace collision? Do I have to take extra
precautions with 2.6.10?
