[linux-dvb] AVerTV-771 not working anymore

i have a quite annoying problem.
Sometimes my dvb-t card works quite well after a boot,
but mostly it errors out with:

mt352_read_register: readreg error (reg=127, ret==-5)
dvb-bt8xx: A frontend driver was not found for device 109e/0878 
subsystem 1461/0771

As you can see i have an avertv dvb-t 771 (i worked on the mt352 driver, 
thanks for wolgang jost for his good work).

My kernel is 2.6.12-gentoo-r6. I think the problem maybe has something 
to do with my mainboard or its bios. I testet some older bios versions 
and the latest one, but the problem doesn't go away. Even 
kernelparameters like noapic, acpi=off and 
pci=bios/nobios,usepirqmask,noacpi don't improve the situation.

All modules are working properly except of mt352, as you can see here:

Does anybody have an idea, how to get this working again?

Thanks for any coming answer.
