Somehow your linux.ko is broken, do you perhaps have WITHOUT_LINUX= 
in /etc/src.conf or /etc/make.conf? 
Check the last modification date of /boot/kernel/linux.ko, does it correspond 
(roughly) to the one from /boot/kernel/kernel?

About the kernel option, try COMPAT_LINUX32. It's a documentation bug.
