Works with latest drivers from [2] (23 Feb 2008). Apart from which tree to check out and use, follow the normal build/install procedure.

Warning: As of 2008-04-28 there is a bug in the current driver, which freezes w_scan/dvbscan. http://jusst.de/hg/mantis/archive/af18967ffcc9.tar.bz2 is confirmed to work fine
