Hmm Allwinner A1X and Exynos 4412 both have integrated Mali 400 GPUs, so there should be at least some GPU support on Linux [1].
There is an unofficial XBMC port for A1X devices which supports the HW Video Decoder of the SOC [2]. I have an A10 device at work, but unfortunately won't be in the office to play around with it for some time.
