Are you _shure_, the Zyxel does IP over raw HDLC ? Last time i looked at 
them (ok, it was some time ago), they were not capable of doing this.

Anyway, i get ~7.2kbps without and ~7.4kbps with VJ header compression
IP over raw HDLC on a 486/66 and even on a 386/25.

No, i don't think this is a limiting factor.
