This is a good question. At present, It only reserves 0-1MB for DOS and
the rest of the memory is available for Linux. It's whatever Linux
wants to use. One thing it does allow is Linux to call DOS interrupts
from protected mode and return.

I am in process of cleaning up the patch series and prepping it for
2.6.27. Give me a couple of weeks and I'll post a cleaner version of the
code with the loader debugger, and I'll submit it to Andrew's MM tree as
patches.
