Package: linux-image-2.6.18-5-686
Version: 2.6.18.dfsg.1-13etch2
Severity: normal
Summary (technical details follow below):
When I added a videocard to my PC (in addition to the on-bord-video
chip), the kernel panics (oops) during bootup. When I manually remove
the intel-agp.ko module (which works with the on-bord-video card), the
problem disappears (the on-bord-chip probably doesn't work then, but
this is what I want anyhow). I guess the module for my new video
card (I guess it's radeon --- see details below) interferes with the
intel-agp module.
Background:
I bought a PC with on-bord video chip. When I upgraded my monitor, I
found that it did not work with that chip. So I added another video
card and ran into this problem. As I don't need the on-bord video card,
my quick and dirty fix is to remove its controller module.

What is written on the screen when the kernel panics? I copied the
information manually. Quite possibly, I made some typing mistakes:
*pde=...
*pte=...

Which video chips do I use? I don't know for sure, but from `lspci` I
guess:
* Display controller: Intel Corporation 82845G/GL[Brookdale-G]/GE
Chipset (this may be the chip that loads the intel-agp module).
* VGA compatible controller: ATI Technologies Inc RV280 [Radeon
9200 PRO] (this is the second video controller that I use now).
Here is the full output of lspci:

Which modules conflict with each other? I don't know. I guess they are
intel-agp and radeon (or possibly modules that are loaded by these two
modules): The system runs fine when I remove the intel-agp module or
when I remove the additional video card that uses the radeon module.
Here is the output of `lsmod` on my running system when intel-agp is
removed:
