The C3 is is not-particularly-high-performance i686-class CPU core.  The
only thing that's really special about it is that it uses relatively little
power, compared to your average modern CPU from Intel or AMD.  The 'Eden'
variants are particularly good -- the 600MHz Eden on my EPIA-ME6000 board
probably performs about as well as a 500MHz PIII -- more than enough for
most tasks -- yet the whole board consumes a maximum of around 22W, under
full load.  Contrast that with the Athlon XP1800+ in my main workstation,
that probably gets through about 50W when it's idle, never mind what the
rest of the board is using :-(

I don't know much about the CLE266.  It includes VIA's 'CastleRock'
graphics hardware and some DVD decoding support.  Almost all the onboard
hardware of the EPIA boards is supported by FreeBSD, including the Firewire
and USB ports (the latter only at USB 1.1 speeds for the moment).  The
CastleRock graphics have some early support in XFree86, but not the MPEG
decoder.  See another one of Matt's pages for the full scoop on getting it
to work with XFree86 on FreeBSD:

You wouldn't want to play 3D games on these boards, or run buildworld on
them too often, but they're more than powerful enough for most other
jobs. I don't know if anyone has tried this, but I would expect the faster
(933MHz and 1GHz) boards at least to have enough grunt to handle DVD
playback even without the MPEG hardware.

Cheers,

	Scott
