Hi,

i am able to use rgb24 on vid0 with fbdev system, without any patches on
directfb 1.4 :) , only thing i had to do was

move /etc/fb.modes file
and export FRAMEBUFFER=/dev/fb/1 (for vid0)
thats it

but with following cons
a] RGB is inverted but no problem with image provider
b] performence is low compared to 16bit over osd0 (df_andi example avg FPS
is 10 where as on osd0 it was 16 )

and Craig

Why you were not able to use devmem system along with davinci driver? as per
my personal experience devmem performs much better than fbdev system.. and i
didnt face any problem in using dvmem over osd0 ..
