Re: Matrox Millennium support (2)

AFAIK this is _not_ possible on both the kernel and the KGI driver, as 
they both set the card in "enhanced" mode, which disables some VGA features.

Hmm - there are two #defines at the to of fbcon-kgi.c:

#define KGICON_USE_MMAP 1
#define USE_VMOPS       1

Try commenting them out to:

//#define KGICON_USE_MMAP 1
//#define USE_VMOPS       1

It helps to cure the same effect for VGA. Though reports say, that Matrox 
should run with it.

CU, Andy
