Hi,
  while waiting on these updates I updated matroxfb a bit
(ftp://platan.vc.cvut.cz/pub/linux/matrox-latest/matroxfb-2.5.63.gz),
so that it now uses fb_* for cfb modes, and putcs/... hooks for
text mode. I have still dozen of changes in fbcon.c which I have
to eliminate (mainly logo painting and cursor handling - for now
I still use revc method, mainly because of I did not make into it yet).
I grabbed your latest patch and started to merge it with my latest work on 
the matrox driver. As soon as I'm done merging my matrox changes I will 
send you a patch right away.

  My main concern now is 12x22 font... Accelerator setup
is so costly for each separate painted character that for 8bpp 
accelerated version is even slower than unaccelerated one :-(
(and almost twice as slow when compared with 2.4.x).
Try the latest patch I released.

  And one (or two...) generic questions: why is not pseudo_palette
u32* pseudo_palette, or even directly u32 pseudo_palette[17] ?
pseudo_palette was originally designed to be a pointer to some kind of 
data for color register programming. For example many PPC graphics cards 
have a color register region. Now you could have that point to 
Does this correspond to the LUT i have in my boards ?

BTW, what is the point in having a pseudo_palette if you can store
the colors in the onchip LUT table.

Friendly,
