Yep, will do tonight.
Ksymoops follow:
ksymoops 2.4.5 on i686 2.4.18-ac3. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.18-ac3/ (default)
-m /boot/System.map (specified)
Warning (compare_maps): mismatch on symbol partition_name , ksyms_base says c0214ba0, System.map says c0150400. Ignoring ksyms_base entry
