No, it doesn't, the fbdev code in the glint X driver is hardcoded for pm2fb.
(and maybe even apus-pm2fb).

No, it has been a long time since i looked at that, and i have no real time
for it right now.

That said, i guess he is speaking about pm2fb + glint X driver, and i don't
know if he uses USEFBDev or not, but like said, the glint X driver is
hardcoded for pm2fb, and was done such, by Michel Daenzer i think, but it was
a long time ago, in order to get it working on powerpc/apus(amiga with powerup
board and Blizzard/CyberVision pm2 graphic board) hardware, so it is possible
that it has some hardcoded stuff needed for the apus specific case.

(but i thnk i have seen a mail from michel lower in the thread, so maybe he
will tell you more)
