I've tested some Windows 3.1x drivers and modified them to enable true color in the highest resolutions.
The supported color depths are 256, 65536 and 16777216 in all resolutions.

Good job. Did you tested that the drivers are stable? Keropi wrote about load crash/freeze problems but it might be specific for his HW config only. Could you give dome mor info how did you add truecolor modes? I try to do so on Matrox Millennium II drivers where I did a registry hack under WinXP to enable 1600x1200/32bpp but I also would like to patch it for WNT4. Under Win3.x this mode works out of the box.

Well, it just was an addition to the .inf file.
Strange enough for some resolutions there already were incomplete sections in both files (for Riva 128 and TNT/TNT2).
