In Driver by GT Interactive, I noticed the 8-bit palettized textures option is grayed out with dgVoodoo2 even (GeForce 4TI card).
A demo of how the setting works is here:

The textures can be seen in use at Night in the Los Angeles map in San Francisco area (there are cheats available to make the map unlocking instant)

Actually it's a problem on the game side. The code checks against a bad pixel format descriptor for detecting 8 bit textures.
I guess an old D3D Voodoo driver described it in a wrong way (only with flag DDPF_PALETTEINDEXED8) but the real, expected format includes rgb too (DDPF_PALETTEINDEXED8 | DDPF_RGB).
You can easily patch the game for that: both in Config.exe and Game.exe, search for byte pattern 0F 85 DA 00 00 00 and change it to 0F 85 DF 00 00 00 (DA -> DF).

Okay that works.
I noticed another small issue as well. In the Config program, I get a dgVoodoo2 Wrapper, 3Dfx Glide and "GPU name" entry. With the "GPU name" entry, the wheels in game go missing, but dgVoodoo2 features like the paletted textures work. Why a pseudo-working dgVoodoo with the "GPU name" setting?

TBH I don't know, I don't get a GPU name entry.

Editing the game.exe crashes the game for me. Is there a particular instance of 0F 85 DA 00 00 00 I need to edit? There seem to be 3 of them in game.exe.
Editing the instance at 20E4C seems to have worked.

I did the first instance

Thanks, that one works for me.
Amazing! Seeing these effects for the first time is great, I can't imagine many people have played with them before, with 8bit texture being unsupported in ~2001. This is real preservation.

Every 3DFX card (starting from the original Voodoo Graphics) did support 8-bit paletted textures, so the feature was definitively available before 2001.
There were some contemporary cards from other manufacturers which supported this as well, like the ATi Rage Pro/XL, S3 Savage 4, Trident Blade 3D and so on. It's just Nvidia that lagged behind, only adding paletted texture support with their GeForce cards.
