There's no safe way to make a driver to get control after the others, if both are modules, so the option is to use the saa7146 driver instead of stradis. > There is no change in searching devices, it didn't check for subvendors before > not even now.

It's vendors' problem, that they don't use this pci registers > (and it's evil) -- i think, that stradis cards have that two zeroed. This is, in fact, a trouble on several video capture boards. A real merge work should be done by migrating stradis to use the generic support for SAA7146. Then, having just one board, those conflicts won't happen. > > regards, > - -- > Jiri Slaby www.fi.muni.cz/~xslaby
