I recommend that you stick with the Atmel or NXP parts.

The AT91RM parts are fairly old. Atmel has a new AT91SAM9260 part
which is listed as "production" and shows stock at Digikey. They also
have the eval board for $560. I can't say why this board is so
expensive. It may have a lot on it, I don't know.

I don't know exactly why the NXP parts seem to be more popular with
smaller designers, but the Atmel parts are very good. We are using
one of the SAM7S parts here and another project is using the SAM7X.
No real issues that made trouble for us. I expect the SAM9 will be
pretty good as well. Check out the Yahoo group, AT91SAM might be a
good place to ask questions.

Thanks for the advice. The only NXP devices that fit our requirements
(must have I2C and SDRAM controller, Ethernet MAC is a bonus) are the
LPC8880 and LPC2468. However, the LPC8880 is BGA-only, which we'd
like to avoid, and the LPC2468 doesn't seem to be in full production
yet and if it is, I'm hesitant to use a brand-new chip considering
NXP's record for releasing buggy devices.

That leaves us with Atmel, and the AT91SAM9260 is the closest fit for
this project. I think we may be able to deal with the expensive
development kit. Will we need to buy a JTAG debugger as well, or does
the AT91SAM9260-EK come with an on-board debugger?
