An expanded list of what works and doesn't work for me (not 
double-tested, and where not specified I'm listing chips rather than 
card mfr/model):

Worked:
- PCI Matrox Millennium II MGA 2164W (PCI card)
- Intel 82810E (integrated)
- An ATI-based AGP card sold as a MIC E-G012-02-1214(B)
- ATI Rage 128 Pro (AGP card)
- ATI Rage 128 (AGP card)
- HP VectaVL PC w/ integrated video, probably either:
         Matrox G250 2X AGP
         Matrox Millennium G400 4X AGP

Partially Worked (got past the blank, black screen but then failed somehow):
- Diamond STL III S540 XTRM32M 82 (AGP card)
- Diamond Spdstr A50 with SiS 6326AGP chip (AGP card)

Failed:
- Trident 3DImage 9850 (AGP card)
- S3 Trio64V+ (PCI card)
- Diamond Viper with Power Weitek 9000/9001 and Oak Technology T9351 
chips (PCI card)
- ATI Mach64 (PCI card)
- eMachines eTower 500i w/ integrated video, probably:
         ATI Rage Pro Turbo 2X AGP
