I just found http://www.cc65.org/doc/c128-3.html which essentially tells me
this is exactly how cc65 configures the 128 by default, so I guess that's
the reason I didn't see any change in my program's behavior after
"configuring" the MMU. :)

There doesn't appear to be any way to get more RAM available without bank
switching.
