No, its:
          Inet --- Router --- Laptop --- PC
         (Inet--Router) --- (eth2:eth0) --- (eth0)

No, the PC.
Again: The laptop has full access to the router via eth2 (wireless). The
PC uses the Laptop as gateway but cannot resolve the nameserver, because the
router is connected to eth2 not eth0.
 post-up route add --host <router> gw <notebook>
is missing in /etc/network/interfaces, which I add always manually (it's
still easier as to install bind on the laptop).
(Would it harm to add such a line by default, even if the <notebook>
gateway is not required for connection?)

Would it be so bad to have a fixed IP list in d-i? Remember that DNS server
are sometimes down (happens approximately twice per year for me for
short time).

OK.
