How about just calling malloc() in a loop until you get an allocation 
that matches all of your addressing requirements, and then free all the 
ones that didn't. Brutal, but it should work if called very early on in 
your startup before anything else has got to malloc().

If you don't have "malloc" then you should have something similar 
managing your heap that could be abused to do this for you.
