I might add my two cents to this thread. I have owned a Voodoo 1,
2,3 and currently 5. Great cards. 24-bit color modes ARE supported
on them, whereas 32-bit modes are NOT.

Voodoo3 BIOS buglist: (what I have found)
- Division by zero when trying to adjust logical scanline width in
  lo-res hicolor modes. (yes I debugged the BIOS)
- Palette changing not synced in palette setting function.
- Hardware scrolling has 4-pixel horizontal granularity.
- Default scanline width in 320x200xY (Y > 8 bpp) is 1024 bytes.

Voodoo5 buglist:
- All the V3 bugs, PLUS:
- double scanned modes draw only every other scanline. These modes
  include: 320x200, 320x400, 400x300, 512x384. All VESA modes, that
  is.

Basic VGA works fine, though.
