Excellent, I'll take a look and see if I can convert the trident driver.

We'll probably need this code for some platforms, but on Linux we should 
make the kernel do it since it's the only software with enough 
visibility into things to make it work reliably.

Or drop ones w/o maintainers? :)

Sounds good to me as long as we get the major drivers converted (intel, 
ati, nv, mga, sis, via) and get it a little soak time.  Merging it over 
to the main tree should make some of the other cleanups a little easier
