Hmm where exactly can you read that info from ?
I quickly searched through sysfs, proc and dev but without much luck  :-)

Should I get android to work correctly it would be nice to automatically 
start android after booting the n810.
Thus if you have any info on setting up wifi automatically from a script 
and what exactly to disable to prevent the system from starting Xomap, 
dbus, hal etc... that would be nice :-)

According to what I've read so far it will be open-sourced as soon as 
the first devices start to appear...which probably won't be anytime soon

But even then that work wouldn't be useless because Google won't release 
a framebuffer driver for Nokia n800/810 ... so if one wants to be able 
to run m5 and future releases, somebody has to modify the current driver 
to be compatible with android...if that is even possible.
