I don't understand - how else can it possibly work then?

wsfb is mainly intended as a way to get a working Xorg up for testing purposes.
I would hope eventually that no one ever runs it, but is instead running a
hardware specific driver, but for the short term I made do as best I could
(and am sure anyone could make it better by putting a few more hours into it,
I just haven't taken the time beyond the initial work of bringing it up).

Sorry, which guesses are you referring to? I'm not sure what you're
talking about.
