That would be good, as far as i remember - the issue is, without these
patches the driver crashes after a while caused by vdr's excessive use
by EIT scanner. So it can only be used without EPG scan enabled. With
that it was running stable. There have been a few different patches
floating around to address this issue.

Let me get to the users of the cards, to test the current dkms [1] w/o
any patches and confirm back to you whats current situation
