updateDVB (the new stv090x-scan) it doing pretty good, works well with non stv0900/stv0903 tuners, no spectrumscan or blindscan, but tuning and analysis of the signal works.
You can find all my projects source on my bitbucket page
Let me know how its working out for you and if you have any idea's on where the project should go.
stv090x-scan and s2-liplianin-v37-udl are now in archive status and wont be maintained any longer.
