I am pretty sure the AMD Alchemy comes in 400Mhz. Not FP though as far
as I know. Uses less than 1W power too, which is just amazing.

A better choice is the freescale MPC5200 (400MHz, PowerPC e603): http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MPC5200B
32/64 bits FPU, superscalar. (max throughput in 64 bits float instruction: 1 instruction per cicle, latency: 3 cicles)
ATA 4 (IDE, 33Mhz), PCI, USB (1.1), SDRAM and DDR SDRAM controler..... (less than 1W power too)
An SBC based in the MPC5200: http://www.pegasosppc.com/efika.php

Some do, some don't. Most embedded once would probably not have FP.

I believe AMD has reference designs for making geode boards.
