PWS500 and Matrox Millenium II

[BERTRAND Joël <joel.bertrand%systella.fr@localhost>]

	Hello,

	I'm trying to use a Matrox Millenium II in my PWS500au running NetBSD 
7.99.1. When system boots, it shows my mga adapter as :

vga0 at pci1 dev 9 function 0: vendor 0x102b product 0x051b (rev. 0x00)
...
drm at vga0 not configured

	Text console runs fine, but I'm unable to start X server. Of course, I 
have built X.org from xsrc. X crashes with following error :

Fatal server error:
AddScreen/ScreenInit failed for driver 0

	Mga driver returns :

	I suppose I have done a mistake... Any idea ?
