There are still some open problems (text mode, hardware cursor), and I missed 
something somewhere, as czech font works only on VT1 console with mga-2.5.65 
(on other VTs there is some font loaded, but character mapping looks broken). 
I have no idea whether it is my problem or James's...

Probably worst problem currently is cursor code: it calls imgblit from interrupt
context, and matroxfb's accelerated procedures are not ready to handle
such thing (patch hooks cursor call much sooner for primary mga head).

At worst, for 2.6.0 I can remove text mode from version for Linus, and maintain
text mode capable driver separately, if we'll find some solution for cursor...
