Well, I think 2.6.10 had a known bug and a matching fix/patch (remove a line 
reading "goto retune;" from drivers/media/dvb/dvb-core/dvb_frontend.c).
I don't know what is wrong with 2.6.11, but I have the same problem as you 
with the following hardware:
saa7146: register extension 'budget_ci dvb'.
ACPI: PCI interrupt 0000:00:0c.0[A] -> GSI 19 (level, low) -> IRQ 185
saa7146: found saa7146 @ mem e1d9e000 (revision 1, irq 185) (0x13c2,0x1011).
DVB: registering new adapter (TT-Budget/WinTV-NOVA-T  PCI).
adapter has MAC addr = 00:d0:5c:22:22:4a
DVB: registering frontend 0 (Philips TDA10045H DVB-T)...

The problems seem to be fixed in CVS though. Maybe someone is willing to 
identify the fix in CVS and make sure it is part of 2.6.12?
