Try dumping the connection attempts with tcpdump like:
tcpdump -pi fxp1 -w /tmp/mydump.cap -s 1600

Then loading the mydump.cap file in ethereal might prove more useful.
Also i've seen a handful or two of commercial routers that simply do not
set the right fields in the packets. I wouldn't be too quick to blame ppp.
