You first need to convert the card to use the busdma API if it's not
using it already, and you then have to deal with endianness issues
(FreeBSD/sparc64 is big endian).  Look at the for more information on busdma.

More specifically, you can look at the xl(4) driver which has recently
been converted to busdma and made endian-safe.

Err, the FreeBSD project is entirely opensource.  The biggest part of
the kernel is MI (machine independant) and thus doesn't have to be
changed to work on other architectures.  A smaller part of the kernel is
MD (machine dependant) and needs to be written for every different
architecture we support.  The sparc64 specific sources of the FreeBSD
kernel can be found in /usr/src/sys/sparc64.

I don't remember whether 3c590 cards are supported by xl(4).  If so, it
should just work on sparc64.  It hasn't been uncommented in GENERIC yet,
but I'll do it a second.  The Intel card won't work on sparc64 yet, but
I'm currently working on the fxp(4) driver for the busdma conversion.
Once this is done, we need to make it endian-safe in order for it to
work on sparc64.
