No idea why it happens, but I started to get similar oops problem
with vanilla kernel.org kernels and during last days 
with head version of dvb drivers.. My hardware is different, Terratec 
Cinergy 1200 dvb-c (w/ ci&cam), and oops messages are also a bit 
different. Before I started to see these the combination of 2.6.16.x 
kernels and hg head drivers were working really well on my Debian 
unstable. Unfortunately I haven't gotten the drivers to work with 2.6.17 
rcs & final at all, just oopses during module loading or player

Here's the oops message with (kernel tainted though)..
