I own a G400 MAX (on a Epox 7kxa mobo) and have had some problems (in Win2k) lately so I've been spending quality time searching the Matrox forums. I can confirm the G400 MAX works fine in FreeBSD, I'll send you my configs if you want but I think the configs previously sent will do the trick. I've got a few points for everyone with a G400 based video card... - The cards have known problems with some motherboards. If you are having problems you should upgrade the BIOS on the video card and motherboard. The latest BIOS for the G400 came out on the 11th June. - Get your updated G400 BIOS from here ... http://www.matrox.com/mga/support/drivers/bios/home.cfm - AGP 4x support in the G400 family is not perfect - apparently the G400 chipset was designed and released before the AGP 4x spec was released. I've seen it said that any G400 with a "4A" in the product code will support the AGP 4x port itself but may have troubles with the maximum memory bandwith. - For confirmation you can search the Matrox forums ... http://www.matrox.com/mga/support/forum/agree.cfm ... for the obvious words and look for posts from a Matrox employee named Louie. Here's one thread in particular ... http://forum.matrox.com/mgaforum/Forum1/HTML/005070.html ... where the sad tale is told. - So you should check out your video card's product code to see where you stand with AGP 4x. Even if your card can support it you should go into the motherboard BIOS settings and (if you can) turn off AGP 4x so only 1x or 2x is used. There's no question that the cards work flawlessly at this speed. If you can't do it at the mobo level there is a Matrox utility (on their WWW) called a "Tweak Utility" where you can knock down the speed at the card. Of course it's Windows based, just like the BIOS updates, but we all know this happens. Once you change the AGP setting from Windows the cards BIOS keeps the setting so it should remain in FreeBSD. I hope something in all of this helps you out. Sorry if you don't like the AGP 4x story but I'm just the messenger, I didn't decide to market the boards as 4x compatible.
