Aha, I though it is mandatory...

Hope so but it may be very restricted. See Bear Windows FAQ where he say:

nVidia GeForce 5xxx/6xxx/7xxx (and newer ones)

PRB: Cannot use custom screen refresh rates, but card identifies itself as VBE 3.0 compatible.
DETAILS: In Video BIOS screen refresh rates switching code is changed. When you try to ask BIOS to set it, BIOS always set default refresh (60 Hz).
FIX: None known.

nVidia GeForce 5xxx/6xxx/7xxx (and newer ones)

PRB: Cannot set any resolution higher than 800x600.
DETAILS: In Video BIOS mode tables - 1024x768 modes and higher are absent or filtered. When you try to ask BIOS to set it, BIOS returns an error.
FIX: Update your BIOS with latest version or patch it.
