However, up until today I've been unable to use it as I didn't have a DVB-T2 signal. This changed on the 15th of June when Craigkelly's digital switchover was completed. Unfortunately the driver isn't available in mainline linux yet, so I've just forward-ported it to 2.6.39. The temp patch is available here.
It seems to work fine; I'm using (an unmodified!) tvheadend as a headend, and XBMC as a network client. Its a pity the actual content is still as poor :)
