Just saw this announcement.
There is a single board computer that has just been announced. Should be
shipping in a couple of weeks. It has an AMD 100 MHz processor, a 10/100
port and a PCMCIA socket, 16MB RAM and 8MB flash (which may change to 32MB
and 16MB before production begins). Power is 100mA @ 12v. It is running
Linux and uses a web interface to configure. Price to be around $300.
It is intended to be a Customer Premises Router for wISPs.
There is another version on the way (6 weeks to production) that will have
3 10/100 ports and 4 PCMCIA sockets.

These could be configured to run LRP also. :-)
