I would think the best way to overcome the resolver stuff is to config 
your own nameserver and put all of the work/ISP nameservers in as 
forwarders (you probably want "options forward-only" too.

I'm not sure how this works in real life though (do you still get a 
horrible timeout while it figures out that the first DNS isn't 
reachable).

The alternative is a ppp.linkup script that sets up resolv.conf.
