I have used the Fedora9.rpm on fedora 11 and currently on fedora 12. The .deb installed on ubuntu 9.xx - though the gui app fails to fully launch - i used the wvdial.conf instead. have a look at http://www.tuxhat.com/linux/reliance-netconnect-broadband-on-linux/
I think I edited menu.1st on ubuntu due to unnavailability of modeprobe
