We work with AT91 ARM chips. I can help there.
OK, now I have a clear deadline to commit a (nearly ;-) bugfree at91 
EMAC ethernet driver.
Success,
Juergen

Help with AT91 platforms would be great. I have AT91SAM7X-EK and
AT91SAM7S-EK boards. What i don't have is any boards with external
memory interfaces. Without that, using the FreeBSD stack is
impossible, which is why you have found all these EMAC issues. So if
you can test on bigger AT91 systems that would be great.

Also, please don't leave you patch to the last minute. We need to work
on a clean way to handle the copy from SDRAM into SRAM for your
platform without imposing it on other AT91 devices which don't need
it. This might take a couple of iterations to get right.

ok. We have boards with an AT91M55800A with NOR flash, SRAM, Compact 
Flash and memory-mapped Ethernet. And we have boards with an AT91SAM9260 
with NOR flash, NAND flash, SDRAM and MII Ethernet.
We also have the Atmel EKs with those processors. I would like to add 
the arm9 board to ecos ... one day.

Our network is the backbone of the system and must be very reliable, 
hence the heavy tests we run. (Our UDP test perl script is GPL if you 
would be interested)

OK.
