Galen,

A (semi) custom linker script is the simplest and most direct way, that
I know of, to manage memory in the way you need. Not finding a specific
mega16 script in /usr/local/avr/avr/lib/ldscripts/, I tweaked one of the
avr4 choices. For each avr architecture there's one for normal
executables, and a bunch of variants. I'm happily using a script based
on the former. It's worth reading the first line of each before
choosing.

HTH,
Erik
