yep, this is a common problem with systems using intel's integrated
graphics - most commonly laptops.  My dell laptop has this exact same
problem.  It IS a BIOS problem.  The bios is only pre-allocating 1MB of
system memory at bootup, instead of 8 (as you want).

This tells you that it's a BIOS problem. The i810/i830 driver is
attempting to tell the BIOS is got more memory.  This is required since
the driver uses the BIOS to programme the video modes.  There is a patch
here:

http://www.chzsoft.com.ar/855patch.html

but unfortunately, it's Dell-specific.  You may be able to modify it to
your needs.  This patch has been included in the XFree86 source, but I
don't know whether it's been generalised to all hardware (or is still dell
specific).  There more info here:

http://www.xfree86.org/~dawes/845driver.html

It doesn't solve your problem immediately, but it's a known problem with
this hardware.  Probably your best bet is really to get the old BIOS from
gateway - maybe dig on their ftp site? sometimes they leave old versions
lying about....
