I have googled and found some technical datasheets and
developer documentation about the marvell pxa27 under this link/webpage
http://www.marvell.com/application-processors/pxa-family/

I also asked lenovo about datasheets (not the short brief productsheet) to get
facts about it. But again, I do not think that lenovo will ever
support me in this case.
if I got some datasheets and if its not against laws etc I will report it here.

That would be nice, hope they got some glues.
