I've thought about this some more and I can't come up with anything
sensible with a generic interface.

The info we need to pass the drivers to probe is os-specific info, I
don't see the point of a generic interface
that is passing non-generic information into drivers. Like look at the
contents of xf86_udev_device, what
in there isn't udev specific? what info should be in there that
another OS would need etc.

Like yes we could rewrite the whole lot, but I don't want another
pciaccess, evolution already, not rewrite and break.

Dave.
