I've a Rage LT Pro on a laptop and got it not working with the RAGE
driver. Also Matan didn't manage. (Well, I guess it's partly due to
the problem, that we both have no time).

It seems that the driver has to be modified to get it working.
So: if you do the necessary modifications, please let me know :-)

There's another solution (which I shouldn't tell you, as I'd like
someone to write the driver):

Use the VESA driver and it will work. I got it here working with
1024x768. Drawback: you may have to compile svgalib yourself with
increased (don't know the name of the definition) definition in
somewhere src/driver.h: there's a definition to 5000 which you've
(was it MAX_REGS or something like that ?) to increase to at least
7000. Recompile, edit /etc/vga/libvga.conf to use the VESA driver
and you'll be happy.
