Do you use ad-hoc mode as well? Can you see a change in cpu use if you do?

Because that would mean it might be worthwile to upgrade the kernel once again to 3.0.4 and do all the module rebuilds for iptables, openssl and ocf once more.

one thing though: CPU Usage went up by about 15% in contrast to the uap module and AP mode.

I am running subversion, apache, trac (xmlrpc and web frontend), mpd and some other tools on the dreamplug.
So far everything is fast enough and it works like a charm.

Storage is an external USB drive that is soon-to-be replaced by an esata drive combo.

The libertas driver is extremely unstable using the 2.6.33 kernel and ad-hoc mode. However using 2.6.38.8 and a properly patched sd-driver makes the dreamplug a happy ad-hoch wlan node.

Thank you for the great directions!
