This probably means your ppp daemon is buggy; are the DNS servers
10.11.12.13 and 10.11.12.14 or something like that?  What are the
non-working ones exactly?

Upstream ppp has fixed this issue but it's possible your distro hasn't
updated with that fix yet.

I'm not sure if knetworkmanager exposes this option, but NetworkManager
certainly supports using custom DNS servers and ignoring what the
provider gives you.  In the gnome applet you choose "Automatic with
manual DNS" and you can enter your own DNS servers.
