for eth0, simply see my last mail about how to manually set it to dhcp.

After this you do not need to care anymore for resolv.conf, since modern 
routers offer you dhcp, which in turn sets the nameservers, when you 
start is on your notebook.

And please note, this is not an ethernet "modem", it is simply an 
internal ethernet card, which will work anywhere, where you get dhcp via 

In regard to pan0, I have no clue, but when you google with "bluetooth 
networking", this should be sufficient.

If you really need to work anywhere, it might be worthwhile to 
investigate a WLAN pcmcia card, if your laptop does not offer WLAN natively.

Kind regards
