No idea, i guess it will be a lot of debug prints and recompiling to find this
out.

It seems i understand the problem and have a workaround that works on v58. The
problem seems to be in QtMoko power management handling. You can set intervals
for dim, screen off and suspend. There are intervals between them and it
always goes like:
dim->screen off->suspend
If you dont specify interval between screen off->suspend QtMoko automatically
places 100ms there. But this is probably not enough and suspend never happens.
The workaround: go to Settings->Power management->select "On battery" and fill
in good intevals - e.g. Dim=off, Display off=30s, Suspend=40s and it will auto
suspend ok. The trick is that Display off must be filled and must be more then
10s less then suspend.

You can use standard debian networking (/etc/network/interfaces) even for wpa2
connections. There are some docs on internet how to do it.
