Just for the record #2, 2.6.38 with KMS + agpmode=-1 + no_wb=1 +
dynclks=1 still locks up the GPU when I play a video with mplayer.

Besides that, like Andreas, with dynclks=1 the resolution is reduced
to be 800x600. I didn't have the opportunity to read the X logs
regarding the S-Video port, but, at least for the user, iBooks
(differently from PowerBooks) don't have user-accessible S-Video ports
(but this doesn't prevent Apple from having inutilized them somehow).


Thanks,
