Hi Andreas,

instead of 

 static inline unsigned int mga_readb(vaddr_t va, unsigned int offs) {
+	return __raw_readb(va.vaddr + offs);
- 	return readb(va.vaddr + offs);
 }

I think you should use the
	fb_readXXX() and fb_writeXX()
functions from include/video/fbcon.h which are automatically
initialized correctly acording to the architecture.

Greetings,
Helge
