"The same problems"?

How can you be willing to claim that there's some generic driver issue
(which is contraindicated by the experience of many other users) based on
such vague descriptions as "slow as hell" and "the same problems".

Uh -- are you *sure* the devices at both end of the link agreed that
it was 100baseTX, and that they both had the same duplex setting?  The
fxp cards have a different PHY than the compaq cards (or the DEC cards)
and duplex negotiation problems between some PHYs and some switches
are very common, leading to almost exactly the type of performance you
describe above.

Hard-wire both ends to 100baseTX and full-duplex and see what happens.
