ARM2/3 arent available any more. They haven't been for years. They need a ton
of glue logic. Age != pricing (in EU/US anyway)

The ones I know about
Running ELKS - so unfinished kernel as yet, but getting there, no networking
no MMU, small apps
801EC86 etc Embedded 8086 chips (Intel/AMD/...)
Some of these are very cheap. Psion sell a box using an embedded
x86 variant to end users for UKP100 (US$160) or so (the sienna)
running their own OS (not linux)
Running UC/Linux - no MMU, strange libc
68451 "Dragonball" CPU - Motorola - as used in the palmpilot
heavily designed for low chip count PDA's
Running Real Linux
Cirrus ARM 7110 - 19MHz ARM7 CPU, on board lcd driver, gpio, ram
decode etc etc. Aimed at PDA's (used on Psion 5)
Motorola PPC - assorted chips mostly oriented to low chip count
communications tasks. ie CPU + 4xSCC + other logic
Mips - various chips but most vendors sell MIPS as a VLSI cell -
ie you do the chip design they integrate all the bits you
want - high volume option only.
One of the real big issues with this is all the modern chips tend to use
advanced packaging techniques making them hard to build onto boards without
fancy tools.
