OK, I managed to get the CVS viafb driver from directfb.org, and it
compiles fine, and inserts into kernel OK but nothing seems to be
accellerated, Mplayer plays it back very slowly, at 13% CPU, using -vo
directfb, (throws the "your system is too slow to play this!!" message),
mplayer plays it back OK with -vo fbdev, at 60% CPU. Softdevice for
VDR OSD is really slow, and just a green strip across the top 1/4 of the
screen. All these things work fine with an nvidia card/directfb.
Some stuff below:
