So you have a Conexant bt878 based DVB budget card, right?

The video4linux patches you got from bytesex.org modify the video-buf 
helper module. The saa7146 driver broke because some function prototypes 
don't match anymore.

Correct. The saa7146 module will be build against a non-matching 
video-buf module.

This is a temporary problem until I get the CVS driver in sync with 
latest 2.6.10-rc1 again.

Nope.

If you don't want the dvb-ttpci driver (if you have a Conexant based 
card you simply can omit it) for the saa7146 full-featured cards, then 
simply disable it in the Makefile.
