This patch indeed fixed it for me.
Module now loads, detects the card and appears to be successful.

However, when I try to tune, syslog shows:

Tuning is not possible here (Kernel 3.0 in use).
Anybody with the same issue?

Reference for the 'normal' users who just want to use their card:
I have now downgraded to 2.6.38 again on my Sandy Bridge board
(sacrificing working reboot...) for s2liplianin does not like
bkl-removal in 2.6.39 and definitely no 3.0-tree.

s2liplianin on 2.6.38 works perfectly with this card. It also has much
better support for my other az6027 than the in-tree-modules (still, no
signal for any DVB-S2 with the az6027).
