I find the ifup* system of scripts to be really nice and powerfull, so I
usually try to get what I want using it instead of writing my own stuff and
I usually try to avoid modifying the scripts (other than writing some
*local ones) to make future upgrades less painful. 

However in initscripts-5.00, I wasn't able to get your scripts to use
custom connect scripts (I need them because my department uses S/Key
authentication on
the dial-in and that's something that neither chat not wvdial can do in any
reasonable way).

I'll attach a patch that fixes this problem (as well as the bug 17388) in a
second.
