Try these two video boards:

SAPPHIRE low-profile ATI Radeon 9800SE 128MB 128-bit DDR AGP 4X/8X Video Card ($60 USD). The model is: 100566L-RD BK-HS

Or the PowerColor ATI Radeon 9800SE 128MB 256-bit DDR AGP 4X/8X Video Card.

Oddly, the MUI can set 2048x4096x32 as the maximum setting.

I set these extra resolutions up in the Ambient v1.41 / MUI 3.9 Settings -> Systems Settings -> Screenmode profiles:

1600x1200 @ 77Hz
1792x1344 @ 69Hz
1856x1392 @ 66Hz
1920x1440 @ 64Hz
2048x1536 @ 61Hz

There some other little things to fiddle with...

Seems to work on most of the OpenGL demos I'm running on it.
