This means: Mouse, Keyboard can be plugged/unplugged as many time as I want at any point, while displays connected over display port only work when connected before starting X (and they don't disappear after disconnecting). Note that stopping X seems to fix this (so no reboot required), but I don't have the docking station myself (this is the Ultra Dock Pro or something - the one that connects at the bottom of the laptop).

I use just simply:
ifconfig_wlan0="WPA SYNCDHCP"

I think without the SYNC you are not waiting for wpa to come up?
I do not know of the /etc/rc.d/* stuff is prepared to deal with
your "country de" either.
