I'm pretty certain that the '595 is a fair bit different from the '593.

I believe that Matt Thomas is writing a from-scratch WaveLAN driver for
NetBSD, and is planning on just using the '586 compatibility mode of
the '593 so that the same code can be used for the ISA and the PCMCIA
versions of the card.  (The only real benefit from using the native
'593 mode, apparently, is slightly finer-grained control of the multicast
address filter... "big deal" :-)
