Arghh. You are right. I was quite sure that I didn't compile a another
kernel in the meantime, but it seems that I've been wrong. Here is the
output with the right System.map. Sorry about that.

Options used: -V (default)
-o /lib/modules/2.2.5/ (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-m /System.map (specified)
-c 1 (default)
