Yes, you do.  The module is called linux.ko and as you can see in the
OP's kldstat listing, it is loaded.  Usually that happens automatically,
so it's quite rare to actually have to type 'kldload linux.ko'

The undefined symbol errors suggest that the OP is missing some
important linux shlibs which should be installed in
/compat/linux/usr/lib -- what linuxbase port have you installed, and
what distro did you obtain those linux executables from?

	Cheers,

	Matthew
