video=matrox:cross4MB works too !

I am lost !!
I've XFree86 Version 3.3.6
I've and ATI AGP video card with an S3 chipset and 4Mb plus the Matrox Mystique
(PCI) with 8Mb.
I've told the BIOS to boot the AGP first. So I boot normaly with the display on
the ATI card. Then the system switches to the matrox (and Framebuffer). At this
time, I move manually the display to the Matrox board and all si right (I'm
doing this test before doing some cabling / modification on the 19" IBM
screen). If I start Xwindows with the SVGA accelerated server then it starts on
the ATI card. If I start it with the FBdev server, I get it on the Matrox card.
I've read some stuff in Framebuffer-HOWTO but I think I've still some
experiment to do.
IFAIK, there is no DRI option for the Mystique ... ??
