I'd like to use nearptr's to access physical memory currently occupied
by video hardware. SOunds pretty simple, no? Well, I've read rumours
that there are dangers involved in setting the NEARPTR flag in my crt0
flags. One problem I have noticed is that when running under gdb, gdb
crashes when I use this flag and try to print out large data structures.
Are there any other possible issues? What's really going on in there?

-Jim.
