work when using a graphics chipset which identifies itself as `VIA CLE266', used in some VIA EPIA boards. Two values need to be patched in the VESA mode information structure: the widths of the modes mentioned above are encoded in a format which was unknown to the VESA module (and to my copy of the VBE spec.) whereas the window memory segment values seem to be just incorrect. I tested this on a VIA EPIA-M9000 and -M10000.
