Most of them get hw accel even without huge grafic card. On embed system 
you don't want huge cpu core that eat lot's of power, so you put hw 
accel to help the cpu.

Omap3 chip on beagle board got one.
The graphic copro on openmoko phone is capable of video hw accel
I wonder if the iphone doesn't get one.
