I was under the impression that VESA 2.0 was out in about 1995 and device
support came later.  If your laptop was produced in 1997 I wouldn't have
counted on it having 2.0 support.

You can never change the mode of the VESA frame-buffer in any significant way
with fbset regardless of anything else.

Try putting "vga=788" in /etc/lilo.conf , read
/usr/src/linux/Documentation/fb/vesafb.txt for more details.
But if vga=788 doesn't work then probably nothing will.
