What I usually do  is:

1) Install the kernel sources
2) hg update in v4l-dvb
3) in v4l-dvb, do make kernel-links KDIR=/path/to/kernel

I too get the patch faillure at this stage, but I've just been ignoring it :)

This'll hook the DVB drivers into the kernel, replacing the DVB stuff there 
already.. all you need to do now is cd to the kernel directory, and do a 
normal kernel configure/compilation. The HG drivers will have been patched 
into the kernel so you should see 'em pop up in there.
