Thanks for the suggestion. Unfortunately, it doesn't fix my problem.

I've been doing some more investigating and I find that w_scan can't 
"get any working frequency/transponder". The output is:

[chris:~]$ w_scan -c GB -x -C ASCII
w_scan version 20121111 (compiled for DVB API 5.5)
using settings for UNITED KINGDOM
DVB aerial
DVB-T GB
scan type TERRESTRIAL, channellist 6
output format initial tuning data
output charset 'ASCII'
Info: using DVB adapter auto detection.

ERROR: Sorry - i couldn't get any working frequency/transponder
  Nothing to scan!!

That test was with the described patch applied to a 3.7.5 kernel. The 
xc2028 code for 3.8.0-rc5+ is identical to that in 3.7.5. I'll try it 
again without the patch.
