You can use more than 16MB of memory safely in an EISA machine as long as
all of your cards are EISA based that do DMA using the bus.

There are quite a few EISA machines I know of with more than 16MB of memory.
Matter of fact, we had one EISA machine here that had 64MB of memory (don't
know how much of it was used by 386BSD 0.1 though)
