loading driver into Linux kernel 3.0.0-15

I have just upgraded from kernel 3.0.0-14, which was working OK. DKMS reports the driver module active in the new kernel but it is not listed with lsmod so I tried to MAKE && MAKE INSTALL again but I get the following error:
make[1]: *** [media-install] Error 1
make[1]: Leaving directory `/usr/tbs/linux-tbs-sources/v4l'
make: *** [install] Error 2
Any help would be gratefully received.
