Because the earlier BIOS would misparse your E820 information so that it 
misses the reserved block.  This is *wrong*, but it just happens to work 
on your machine, probably by pure luck.

I notice your BIOS version is A01.  You may want to look for a newer 
BIOS, especially since someone else said they had the same machine 
without this problem.

As I said, I think a modification to linux.c32 -- specifically, the 
COM32 library -- could make this work, but I can't promise any timeline 
on that.  In the meantime, this is an extremely odd memory configuration 
and I find it hard to believe it is intentional.
