Sure, as long as you don't make any ROM calls, feel free to run in
32-bit mode.  Seems the ROMs that are out there won't handle it, and so
far Apple has not said that they will be providing a RAM-based OS to
get around this.

Including Apple.  Until they either provide a cheap ROM upgrade or
switch System 7.0 to RAM-based operation (which ought to be plenty fast
enough with a decent hard disk to boot from) no one will be able to run
in 32-bit mode.
