Hello.
I did a recent install of Debian etch on a system with an nVidia
graphics controller. I used module-assistant to install the nvidia
kernel module, and under kernel 2.6.18 from the install, that all
worked fine.
A few days later, I upgraded to kernel package 2.6.18.2-686 (from
lenny) to resolve a problem with the on-board audio controller:
Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev
01)
The kernel upgrade did indeed resolve the problem with the audio
controller, but it meant a re-install of the nvidia kernel module. I
tried to do that as follows:
% aptitude install nvidia-kernel-common
% module-assistant -i prepare
% module-assistant a-i -t -f nvidia-kernel
However, the build failed. The crucial error seems to be this (from
/var/cache/modass/nvidia-kernel-source.buildlog.2.6.21-2-686.1183784666):

The compiler used was gcc-4.1 version 4.1.1 (the kernel seems to have
been compiled with 4.1.2), but the error-message seems to suggest that
the issue is in some sense legal rather than technical.
(There is a similar bug report---No. 430577---against the
nvidia-graphics-drivers-legacy-71xx
package.)
Has anyone else encountered this problem, or does it come from some
stupidity on my part? I could use the nvidia installer, I suppose,
but I'd really prefer to do things the Debian way. Does anyone know of
a workaround?
Extensively discussed here:

The problem is that post 2.6.18 Debian kernels have PARAVIRT_CONFIG and
nvidia does not like that.
You can either rebuild the kernel and turn that off (Note: but in that
case I had hard hangs in qemu!) *or* use the descriptions in that page
to rebuild the kbuild .deb and install nvidia so it does not mind paravirt.
You'll hit the problem both with m-a *and* the nvidia installer.
