The SAA7146 is supported by Manu Abraham's driver ([]). Some people in this (german) VDR board added this card to the driver at the end of april 2009. One Day later the development was committed to http://linuxtv.org/hg/v4l-dvb.
However, this is still some initial support an might need some more testing.
[Update 2014/04/22] Card drivers are in kernel now, no special driver needed. Works great. For Diseqc you might need to use a patch from Guy Martin. At least I do ;) ([])
