heissan!
Can you try attached patch and report?
This patch is a little bit unready due to changes needed to zl10353 
demodulator driver. I have no knowledge what are registers 0x8e and 
0x90-0x96 (please help) but I have strong feeling that those are 
associated to the AGC2 functionality. I think I will put those under the 
agc2-config-switch and send this patch again later. Any ideas are welcome :)
Patch is done against current gl861 devel tree at 
http://linuxtv.org/hg/~aapot/gl861/ .

Thanks for Markus and Aapo for helping!

Regards Antti
