Just looked a bit into the DOS32AWE "source code": it's an IDA disassembly, absolutely awful!

It's not explained what this program does to make pm games compatible with AWEUTIL, but I'm pretty sure that it doesn't enable port trapping - that's too complex to be added to a disassembly. Perhaps it just ensures that NMI is routed to real-mode? That's something that HDPMI does as well. Also possible is that it uses debug IO watchpoints - this could easily be checked ...
