There are a couple of incompatibilities that come to mind:
1. Direct writes to the virtual linear frame buffer at 0xD0000000
don't work any more. There's no trivial workaround for
this, AFAIK, due to DPMI shortcomings.
2. The stack size is no longer unlimited. This is not a big
problem, since you can request a bigger stack size at start-up
with the "_stklen" global variable (see the FAQ 15.9).
