Since 2.5.51, when rewrite came in...

You can get patch which reverts most of James's work at
ftp://platan.vc.cvut.cz/pub/linux/matrox-latest/matroxfb-2.5.59.gz.

I was for five weeks in U.S., so I did not do anything with
matroxfb during that time. I plan to use fillrect and copyrect
from generic code (although it means unnecessary multiply on
generic side, and division in matroxfb, but well, if we gave
up on reasonable speed for fbdev long ago...). But I simply
want loadfont and putcs hooks for character painting. And if
fbdev maintainer does not want to give me them, well, then
matroxfb and fbdev are not compatible.

I refuse to remove features from matroxfb driver, and textmode
support is one of current features (needed and required to be
able to run VMware on fullscreen - and as main part of my
job happens in VMware...). So there is couple of choices:
(1) new maintainer, or
(2) remove matroxfb from kernel, or
(3) persuade me that I want to write matroxcon and forget about fbcon at all, or
(4) something else I do not know about.

Besides that with that strange additional copy in accel_putcs
I get much slower output than with 2.4.x... and although I
understand that for 2.6.x we'll all have faster computers than
we had for 2.4.x, I still think that speed should be primary
concern, and code extensibility and readability secondary.
But well, I told it dozens of time, so why I bother. I do
not want to end up as Larry.
