Oops while running XFree, 2.4.17-rc2

I have encountered an oops while running Xfree 4.1.0 and doing everyday work (debugging a program with ddd). It resulted in a complete lockup (as it was X), but I could still login via ssh.

I do not know if the attached ksymoops output is of much help to you, I see that it references often to NVDriver, so maybe it is an nvidia problem, but as I am not sure I'm posting it here anyway.

Kernel: 2.4.17
Distro: Debian Sid
Gcc: 2.95.4
modutils: 2.4.12

ksymoops 2.4.3 on i686 2.4.17-rc2.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.17-rc2/ (default)
     -m /boot/System.map-2.4.17-rc2 (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

Error (regular_file): read_system_map stat /boot/System.map-2.4.17-rc2 failed
