I tried this patch, on 2.6.24-23-rt and 2.6.31-14-generic
.
On the first, it appears to work fine. Thanks again Rob!
On the second, while the kernel seems happy I am unable to get any
applications to tune the card, when I use the latest v4l tree + Rob's
patch (40705fec2fb2 tip).
* dvbscan fails with 'unable to query frontend status'
* vlc is unable to tune as well
[0x9c2cf50] dvb access error: DVB-T: setting frontend failed (-1):
Invalid argument
[0x9c2cf50] dvb access error: DVB-T: tuning failed
[0xb7400c18] main input error: open of `dvb://frequency=177500' failed: (null)
* w_scan fails a bit more informatively
w_scan version 20090808 (compiled for DVB API 5.0)
using settings for AUSTRALIA
DVB aerial
DVB-T AU
frontend_type DVB-T, channellist 3
output format vdr-1.6
Info: using DVB adapter auto detection.

Presumably this is all understood and expected (i.e. application
authors are updating their code?)
Is there a way to build with the API set to version 5.0?
I was able to use vlc and w_scan ok with Rob's module option
workaround and the stock modules from ubuntu. I will have a go at
building their source + Rob's patch.
