After a lots of kernel compilation, it seems bug have been fixed (for myself at
least) since linux-2.6.25rc3.
Using git bisect, it seems the following patch fixed the bug:

This patch seems to fix MSI handling for NVidia chipset.

Next step: backport the patch to 2.6.24-16 (should be fairly simple) and check if it fixes the bug definitively
