It's easy to do a lot of header prediction code in the link-level driver;
most of the packet doesn't change much, especially for TCP ACKs.  See, for
example, RFC914, Farber, D.J.; Delp, G.; Conte, T.M., ``Thinwire protocol
for connecting personal computers to the Internet.''  It is probably better
to do that in the host, but doing it (or equivalent) in a Trailblazer modem
would help siginificantly.
