sound more like lcd/hdmi modules were not loaded (modprobe)

what's the intended difference between sun4i_defconfig and 
sun4i_crane_defconfig? the later is clearly more android-ish.

thanks, I've added it to the lichee-3.0.8-sun4i branch [1] , and sync'ed 
with the one we had forward-ported from 2.6.36 in 
allwinner-v3.0-android-v2 [2], but ended up been almost identical (see 
[2]) so I really doubt it fixes any of the reported problems at all.
