Garbled screen in Windows 2000.

[jms]

I am having some problems getting my G400 DH to function in Win2k pro(yeah, I know they are beta drivers). After installing the drivers, the screen becomes garbled(lines++), just after the login. It is almost like when you are using too high refresh-rate(which I have checked that I don't). The NT-drivers seem to work fine though, at least in 2D.
Any ideas?

My system:
AOPEN AX6C Pro II (millenium ed.)
Celeron 366@550.
128MB RAM
G400 32MB DH
SB Live player 1024
KTI NIC

My IRQ-list(in norwegian, but you should get the general idea ).
0 Tidtaker
1 Standard 101-/102-tasters tastatur, eller Microsoft Natural Keyboard
2 Programmerbar avbruddskontroller
3 (ledig)
4 Kommunikasjonsport (COM1)
5 Matrox Millennium G400 DualHead - English
5 IRQ-holder for PCI Steering
6 Standard diskettkontroller
7 (ledig)
8 CMOS/sanntidsklokke
9 Creative SB16 Emulation
10 KF-230TX/2 PCI Fast Ethernet Adapter
10 Intel 82371AB/EB PCI to USB universell vertskontroller
10 IRQ-holder for PCI Steering
11 Creative SB Live! Value
11 IRQ-holder for PCI Steering
12 PS/2 Compatible Mouse Port
13 Matematikkprosessor
14 Primær IDE-kontroller (dobbel fifo)
14 Intel 82371AB/EB PCI Bus Master IDE-kontroller
15 Sekundær IDE-kontroller (dobbel fifo)
15 Intel 82371AB/EB PCI Bus Master IDE-kontroller

Forcing the G400 to IRQ 10 or higher did not help.
Any help appreciated.

Suggestion #1:

Make sure you're using Win2k Final (2195).

Suggestion #2:

Force ACPI. You'll need to modify a file (there are instructions elsewhere in here, run a search) and reinstall Windows.

Suggestion #3:

Make sure you have the Matrox Beta 5.00.0x and not some earlier driver.

Then come back if it's still broken.

Listen up, you primitive screwheads! See this? This is my BOOMSTICK! Etc. etc.

Well, I am using Win2k final, and the latest drivers. Also tried reinstalling with ACPIEnabled=1, no difference. The funny thing is that everything is fine until I log in, then all hell breaks loose. This is with no apps. at all installed.
