can't access video memory?

Hi all,

As an experiment I tried accessing a part of (shared) video memory
on my system that is not being used for display data, and this caused the
kernel to crash. I have 6 megs of space and the display is using only half,
but accessing above the 3 meg mark causes the problem. Accessing
the lower 3 megs works fine.

Does anyone know what might cause this?

Thanks,
Zack Smith
