Not that I have found.  For my particcular use, I ended upo removing the
default route and added routes for the local networks I have here, and
let pppd set the default.  This means I can't get past my local lan,
unless dialed up, but this suits my needs.  I know on my laptop, I
always had to shut off my networking to get PPP to work, but I thought
it was because of the lack of connection through eth0, not the route... 
learn something new each day.
