HI!

Ignore this patch, this is early version that breaks analog part just
to get dvb-t working. 

I had posted improved patch (I called it v17, should be on this list as well) 
with early supports for both analog dvb-t and radio on 2.6.33.4 (also the remote, but the 
IR system had changed so we may fix remote later... but that's easy :). We
have another issues

Patch v17 which works on my case from cold reboot and at least first
time VDR is started. Subsequent restarts of VDR may prevent DVB-T tuner
from changing frequency - it stays and receives the previos frequency
at which VDR stopped. But sometimes after frew minutes VDR starts working
again tuning to different freq - strange behaviour really maybe it's not
only because of compro patch, could be firmware issue too)

While Samuel is testing this he had some positive results but so far but he needs 
to preinitialize the card with window$ before the firmware gets loaded :(.
I don't need this (anyway my motherboard removes PCI power for 2 seconds during 
restart so I even cannot try such intialization method)
