I have a simple program that maps a frame buffer into user space and
draws an image
onto the fb.

This program worked fine under 2.4.3 however under 2.4.5 the program
runs but nothing appears on the FB. The memory I am writing to does not
appear to be the frame buffer.

Nothing has changed in my fb driver so I am wondering if anything has
changed in how memory is mapped via the kernel?

Thanks for your consideration
