there are a couple of risky areas on the tablet pcb, due to datasheets and app notes simply not being available: the usb audio and the usb camera IC. these are a CM108AH and a Vi Micro VC0345 respectively.
I found this datasheet with duckduckgo: http://www.hardwaresecrets.com/datasheets/CM108AH.pdf
and with google: http://www.stet.com.cn/%E4%B8%AD%E6%98%9F%E5%BE%AE%E8%A7%86%E9%A2%91%E8%8A%A...
yes, me too, here: http://hands.com/~lkcl/eoma/kde_tablet/VC0345TLNA-1102-V10-EN.pdf and http://hands.com/~lkcl/eoma/kde_tablet/CM108_DataSheet_v1.6.pdf and i also found an app note for the VC0345: http://hands.com/~lkcl/eoma/kde_tablet/VC0345_app_notes.pdf
i believe i even also found someone who had released ORCAD schematics for the CM108AH (looks that way from the list of files here http://hands.com/~lkcl/eoma/kde_tablet/)
but i would preferr to have something actually in my hands, or close-up hi-res photos, as i can then be much more confident that i have a decent layout.
