[directfb-dev] Using 32MB of your Matrox card

[Denis Oliver Kropp]

Hi,

did you ever wonder why matroxfb only lets you use 16MB
of your 32MB Matrox card? Here's a patch which enables
the full 32MB (it works with DirectFB, the matroxfb
developers were just too lazy to use the DSTORG and
SRCORG registers).

-- 
Best regards,
  Denis Oliver Kropp
