Since it's about developping a library for GNU Pascal, it's on-topic.
Please go on - it's very interesting.  :-)

The admin.

It has its own memory scheme.  Well, I wouldn't call it "proprietary"
since everything in the Linux kernel is FREE. ;-)  Memory in Linux is
much easier than in DOS because it uses a flat model - just forget about
segment addresses, selectors and such.  For details use the kernel
source - it is always with you ...

Your plan looks very good; just a general remark:  Be careful when
porting things from DOS to Linux.  Some of the most useful features
of DOS, DPMI for example, are just a workaround for other things
that are implemented in a much cleaner and easier way in Linux.  :-)
