Like "DOS386" wrote "* VESA 2.0 deleted fixed mode numbers"
The standard defined VESA mode numbers are only for VBE 1.xx, because starting with VBE version 2.0, VESA will no longer define new VESA mode numbers and it will no longer be mandatory to support these old mode numbers (vbe3.pdf from vesa.org).

Yes i have used it, but not in 1680*1050, only in 1920x1200 resolution (16:10 for to fit the native resolution of my 28" LCD from HansG) under pure Dos together with two cards with the PCI-Express format!

The cards are a NVIDIA GTX 295 from the manufacturer Colorfull and a ATI/AMD Radeon 7950 from the manufacturer Sapphire.

I use it with a MSI Geforce 4 Ti4200(VBE3;AGPx4;64MB) together with a 19" CRT from Samsung and a 19" CRT from Samtron both with 96 khz, 160 hz capacity, both with a prefered resolution of 1280x1024 with 85hz.

I use it With a resolution of:
640x480 and a resfreshrate of 160 hz
800x600 and a resfreshrate of 140/144 hz
1024x768 and a resfreshrate of 100 hz
1280x1024 and a resfreshrate of 85 hz.

And here are the CRTC timing values(of the CRTCInfoBlock; only for VBE 3):
