I have an old Cornerston card and monitor, capable of 1600x1280x1.  Really
nice.  It maps into memory as a 512k chunk of memory (I know, I know, that
isn't 512k worth of graphics).  It's got one minor problem making it useless
for me (namely, reads of the odd bytes aren't possible), but they had the
right idea.

There is at least one video card for EISA which maps into 0xd0000000, I
believe.  Takes a megabyte there.
