Mystique SaTiX DVB-S2 & s2-liplianin & Ubuntu 9.04 64 bit - modules load but tuning not successful

[Thomas Kernen <tkernen@deckpoint.ch>]

Dear team,

I'm installing a Mystique SaTiX DVB-S2 PCI card (apparently an OEM 
version of KNC DVB Station S2) in a box running Ubuntu 9.04 64bit. 
(2.6.28-11-server #42-Ubuntu SMP Fri Apr 17 02:45:36 UTC 2009 x86_64 
GNU/Linux)

I've pulled the latest s2-liplianin code from:
http://mercurial.intuxication.org/hg/s2-liplianin

I was able to compile and the modules do load, but I don't seem to be 
able to tune to anything. Note that I've only tried to tune to DVB-S 
transponders for now.

lspci -vvv shows the following:

Done.

Note: Card and sat feed are known the work, I've tested it under Windows 
without any issues and I have a Skystar 2 in this server that works fine.

Any suggestions what may be the issue and how I could solve it?

Thanks
Thomas
