In a post on CompuServe, an ex-Apple employee said that the only ROM you could
do this with is the fx ROM, if it is doable at all.  According to that post,
the fx ROM checks the hardware to see if a given feature is available.

If someone with access could check this out and post the results, it would be
a great service to a LOT of people.  At least they would know it is technically
possible to get a 32-bit clean ROM upgrade.
