As far as I understand, when having vga=ask in lilo.conf, entering the
video mode number at startup _HAS_ to be done in hexadecimal, but without
the leading 0x. (you can't enter more than four numbers there). Also, this
is a kernel issue rather than a lilo issue because the kernel is already
booted at this point.
I suspect that you are using a stock kernel that comes with your
destribution, and not your own custom kernel with frame buffer support
built into it. Or may be you have recompiled your own kernel, compiled
frame buffer support, but not turned on VESA support which is one of the
options in the frame buffer support menu.
What is the kernel you are using?
I am running 800x600x256 on a Compaq Presario without problems. First I
tried vga=ask and 0303 at startup, and later replaced this with vga=0x303
in lilo.conf
