As far as I know there is already a free driver for the framebuffer
available (omapfb), what already makes the OMAP3 even with anything else
that's been considered (the S3C64xx doesn't have accelerated graphics with
free drivers either, does it?).
I also heard that a free driver for the DSP will be available till the end
of the year, if it isn't already.

Like mentioned in this thread before it also seems, that there are MCPs
available - so is there any argument, despite having to pay for the PowerVR
in the OMAP without using it, for the S3C?
The OMAP is a lot faster, has a lot more features and doesn't come from a
company that doesn't care about open source the slightest bit.
