If you don't have internet connection via eth0 (if you access only LAN via eth0), then leave out the default gateway in your network configuration (blank or 0.0.0.0 will hopefully work.) Then, when eth0 comes up, it won't have the default gateway entry, and it won't conflict with ppp0. How you configure eth0 depends on your distribution.
