Geek Times just posted some additional information on the Applied Micro (formerly AMCC) APM801xx series:
including a link to an APM801xx presentation:
Page 2 of the presentation gives a lot of technical specs, such as:
PPC405 core with 16KB I and D caches plus 256KB 2nd level shared cache.
128KB on-chip SRAM.
16-bit DDR1/2 SDRAM with optional ECC.
Two one-lane PCIe, one shared with SATA.
Two 10/100/1G Ethernet MAC with TCP/IP assist.
USB 2.0 OTG w/ transceiver.
LCD controller (no details).
Pretty good for $10, except for 16-bit SDRAM interface.
They announced pricing on the development kit: $800, as I feared. Obviously they don't want to compete with BeagleBoard and Freescale Tower.
