The 3c590 uses the 'vx' driver which is PIO/MMIO only.
If it compiles on the sparc64 I suspect it will work fine.

is there any way to get an x86 nic work under freebsd/ultrasparc?
if so, whats the work that i have to do?
please advice
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
http://www.FreeBSD.org/projects/busdma/ 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.
is the freebsd-sparc kernel not open source? i cannot compile/custimize it
myself?
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.

Hello,
I am a newbie to freebsd, I want to clarify something before I get into
using it.
I plan to put freebsd5 on a sun e250, this is a pci based ultrasparc
machine, but at the same time, this machine has a non-sun hardware, which
is a network card thats originally for x86 machine. This card is working
probably under solaris w/ some non-official driver, is supported under
linux/x86. My question is, will this card, intel fastethernet 100, or
3com590 work under freebsd/ultrasparc w/ some tiny tinkering?
It's unlikely, since the drivers for those cards are commented out in
sys/sparc64/conf/GENERIC. The drivers probably need work to use busdma.
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.
Cheers,
Maxime
