Almost *every* PPP implementation used today by ISP's support
Predictor-1 compression, although it appear Linux doesn't.  Get your ISP
to update the PPP implementation they use to something more modern,
since using compression significantly increases throughput.  Also, the
way PPP is setup, if a implementation doesn't support compression, it
should be telling your client that it's unsupported, and not fake it which
causes the link to fail.

The bottom line is that your ISP's PPP implementation isn't just old,
it's also buggy.
