ATMel are just releasing a 400Mhz ARMv5 Micro Controller named
AT91SAMG20
It is an MCU not a CPU and only requires External memory Chips and an
external Network Phy chip, everything else is on the MCU.
I have been testing it against the 200Mhz TS-7xxx (Linux 2.4) and it
is 3 times faster at number crunching, partly due to twice the clock
speed , eabi and the enhanced DSP instructions in the ARMv5.
It also has both USB Host and Client ports, SD Interface, Serial,
10/100 Ethernet.... etc
The MCU only costs $7 and the memory is around $4.
Schematics for the evaulation board are freely downloadable from
ATMel.
It is FULLY open source! no precompiled modules or FPGA code like TS.
The free GNU cross compiler is available from Code Sourcery.
