I have handled this bug with Denis, so his additional findings are results from this.
I have tried to reproduce it but I do not have the hardware he has.
It is a bug in vesafb or VESA mode setting.
I am not able to reproduce this bug on Trident card, 3dfx card, Permedia 2,
ATI on-board card (all using vesafb driver).
The current status is that I will try to find someone with
the NVidia GeForce 4 MX 4x0 card and borrow it. I hope that
Denis' card has some kind of reference board BIOS and not
BIOS modified by the card's vendor.
Regards,
Krzysztof
