What is needed for AVR-GCC to support the AT90CAN128 () that isn't  
already provided by the Atmega128 support?

That is, why not just use

-mmcu=atmega128

for the AT90CAN128?

That's what I was planning on doing; is there some reason why that  
wouldn't work?
Did I miss an important detail somewhere (uh oh... gotta read the  
datasheet)?

You might need to supplement avr-libc by adding some register/bit  
definitions for added CAN hardware or maybe slightly different linker  
scripts, but this can be done by the user and has no impact on AVR-GCC.
