./makelinks "path-to-kernel-version-to-be-patched"

do your regular style of make and make install in the kernel src directory.

Okay so far ..

after that do a $modprobe dst
do a $modprobe dvb-bt8xx

You can read the documentation here..

For CI support you can go through this one..

CI support ie, the userland stuff is not ready yet, but hope to be there 
very soon ..

After this you can use scan to see whether it tunes good

You might as well as read the documentation, how it is supposed to work ..
