Okay, I'm running XP SP2 here, with DX9.0c

After my Hercules R9800 Pro 128MB died (and is now on it's way to Hercules for RMA), I installed Matrox G200 + Voodoo1, since my V2's were at school (to play UT  )

Today, I brought 2 of them home, one being Creative, one some other brand, both following the reference design anyway.

The problem is, that I can't seem to get them work.
I've never installed V2's before in SLI setup, so help me out here please  

Okay, I installed FastVoodoo2's, the latest ones from falconfly.de, and it installed drivers for both V2's (both visible in device manager), but the tools only allow me to set resolution to 800x600 max, which makes me think that SLI isn't working here for some reason.
Also, nothing works, all the 3dfx demos and Unreal just stop responding.

Did I do something wrong?
Are some cables wrong?
The cables go like this: Passthrough cable from G200 to V2 installed "above" the other, monitor cable plugged to this V2. SLI cable going between V2's.

What I've done wrong?
I plugged the V3 PCI card in, boot to windows, it recognizes it, boot.
then I installed latest AmigaSport drivers - when it was installing the tools it whined something about couldn't register some components, okay, I just click ignore, and reboot after done.

Everything seems to be fine, but when I tried 3dMark2001 SE, it didn't show Voodoo3 option in the rendering platform part..
Then I thought something just went wrong 'cause the it couldn't register some 3dfx tools components, so I uninstalled the tools and card, boot to safe mode and manually install the amigasport drivers, boot to windows and try again, but no luck, still no V3 in rendering platforms.
then I tried to set vid card priority in bios from AGP/PCI to PCI/AGP, and everything went fine until it was going to log in - the screens stayed black until suddenly it throws a bsod on me, some radeon thingie (probably RadClocker)..

What did I do wrong?

I was contacted by someone on another forum about this, his sister rig is having problems with V3 3500TV she's using - sometimes when booting the monitor goes to sleep mode and mobo screams about "no gfx card present" or something like that.
With her previous mobo, KT133 based, there was no problems.

So is this known problem with V3 3500TV and Abit KR7A-R, and if it is, is there a solution?
