I had already mailed to mj@atrey.karlin.mff.cuni.cz but got

"How to Get Your Change Into the Linux Kernel or The Unofficial
Linus HOWTO"
Please give me some feed back (damien.benoist@epita.fr) thanks.
kernel: 2.2.17
pb: // 0 does not work with ega/vga adapter and mono display
how to duplicate the pb:
compile the kernel with the following options (module or not):
- vga console
- parallel port
use the following hardware:
- monochrome display
- ega/vga adapter
- a // port at 0x3bc
changes:
- region size for ega/vga adapter with mono display (12bytes
instead of 16).
