It happens for me too. Here's the output of ksymoops.

ksymoops 2.4.5 on alpha 2.5.67. Options used
-v /mnt/linux/linux-sx164-2.5/vmlinux (specified)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.5.67/ (default)
-m /mnt/linux/linux-sx164-2.5/System.map (specified)

Error (regular_file): read_ksyms stat /proc/ksyms failed
No modules in ksyms, skipping objects
No ksyms, skipping lsmod
