I'm not sure I did this right, but here is my attempt.  I ran a 
'ksymoops' and gave it a couple of the errors.  The parts that look 
somewhat recognizable are the sk98lin, which is a Syskonnect gig over 
copper card.  It is the only module I have running on the system.

ksymoops 2.4.0 on i686 2.4.9.  Options used
      -V (default)
      -k /proc/ksyms (default)
      -l /proc/modules (default)
      -o /lib/modules/2.4.9/ (default)
      -m /boot/System.map-2.4.9 (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.
