I've missed the initial discussion, as I understand it currently:
Several apps
nslookup is working. (I didn't see anything in this thread using
nslookup - thats been done right?)
Firefox is working once ipv6 is disabled.
Everything else (tested?) needs numeric ip addresses.
Mandriva works.

It has to be dns...

A couple of ideas - the first thing I check with wierd networking
problems is described better than I can at
http://lwn.net/Articles/92727/ - TCP window scaling problem that bit
lots of people including me (with 3 consecutive adsl routers).
/proc/sys/net/ipv4/tcp_window_scaling is where that setting moved too
now. Ubuntu defaults to 1.
It doesn't sound like your problem (numeric/firefox working), but the
distribution network setup defaults may be different.

I might try sticking the other network card back in the box and test
the other nic.

I've had 3 separate problems with ADSL routers recently running some
gateway protocol for 'adsl autoconfig' under both windows and linux.

Every case was solved by manually configuring the adsl dhcp server to
server up your isp's dns servers instead of the routers dns
forwarding.

Otherwise Synaptic and Evolution are Gnome apps, is your home
directory 'fresh' with gnome settings? or have you maintained it from
a previous installation.
