And which CPU to choose for other devices? I prefer to not touch Freescale i.MX families as they lack good mainline support. OMAP looks better but are hard to get is small quantities. Everything looks like arm926 based cores are the simplest to buy still.

There are a bunch of gcc patches to work around the bugs but I still don't trust them. Freescale iMX353 CPU is pretty much the same price, faster and has an ARM standard VPU.</p> The floating point hardware in that CPU is very broken.
