It's also interesting to note that some video boards may not work with
more than xx Meg of RAM.  This is likely more a problem with older cards
than newer ones.  I had a Diamond Speedstar 64 when I first began using
Linux and 12 Meg of RAM.  This wasn't a problem as the memory aperature
began at 16 MB boundary, I believe.  I ran into this problem when I
added 16 Meg in the spring of '97 and boosted this system to 28 MB. 
Suddenly I had a garbled screen in X, while Win 3.1 was OK.  A little
looking in the XFree docs revealed the above boundary information.

The X server for the Diamond cards have an option available in
XF86Config to specify the video memory apperature.  A little guessing
and playing found that by setting this to 32 MB, my X was restored. 
Later I installed my current ATI Graphics eXpression and this little
problem went away.

Just one more thing to consider when upgrading a system.
