don't know how to fix it, but upping PLEX86_MAX_PHY_MEGS to 64
kills it too. I tried several months back, and searched the code for
a reason for the limit, but none was obvious.
You're probably right about the BIOS capping this -- I didn't have 
tools for building BIOS back then, so wasn't thinking BIOS!

I'd assumed it was a limit on the page-shadowing metadata, but couldn't
see any data structures that backed this up

Good luck, I'd be very interested to find out where this limit hides
