The most likely cause of this is differences in the configuration of the
two installations.  In general, a good way of seeing what these
differences are is:

	* boot installation A.
	* mount root filesystem of installation B under /mnt
	* Run diff:

		# diff -ruN /etc /mnt/etc

Argh!  Now you can't check for diffs now :(

More details on the setup of ppp, your DNS resolver setup, and any
errors you're seeing while connected please.
