Well I think the Cirrus Logic 5440 maps it's frame buffer to the 14 MB
mark and while it does cause troubles it's been worked around.  I'm
not sure if it's the CL 5440 or some other card but I know that there
is some card out there that does this and in 14+ MB systems it is a
pain but solveable.  Don't ask me how I just read about it somewhere
(I think when I was installing Linux but maybe not).
