well I do not have your hw but can you confirm that you have successfully booted a recompiled kernel....based on that guide to have the correct modules?
2) if you have the kernel sources you will also find
/usr/src/...//Documentation/video4linux//README.saa7134 which offers extra advice.
Build
=====
Pick up videodev + v4l2 patches from
http://bytesex.org/patches/.
Configure, build, install + boot the new kernel. You'll need at least
these config options:
CONFIG_I2C=m
CONFIG_VIDEO_DEV=m
Type "make" to build the driver now. "make install" installs the
driver. "modprobe saa7134" should load it. Depending on the card you
might have to pass card=<nr> as insmod option, check CARDLIST for
valid choices.
