That wont work.  I read some spec that demanded continuous ram from
0-16MB, and I thus inferred that I could put a hole after 16MB.
Unfortunately after I did this, I found that it broke some linux
installers.  I believe they had a large initrd which consumed more
than the first 16MB of ram.

Putting the hole at the end of ram definitely works though.
