One way to solve it would be blacklisting the driver module for the 
winfast to prevent autoloading and add modprobe $(winfast_driver) to a 
start script (for example /etc/init.d/local) which runs after the 
autoloading of the other drivers is completed.

2.6.26 will have a per module option to specify the the preferred 
adapter number ordering. The drivers from the v4l-dvb hg repository 
have this option too.
