Can you define "very heavily used" ?
Have you considered aggregating the lightly-used segments in a slightly
more modern switch (e.g. a 3524XL), configuring a trunk port from the
switch to uplink multiple VLANs to a single GigE physical interface on the
Alternately, if you really do need router throughput at or above 1000Mbps,
you might want to consider a purpose-built gigabit router from Cisco :)
Both suggestions are under the assumption that the "router" is not primarily
intended as a security separation between subnets.

We are very happy with the ""Intel PRO/1000MT" quad copper GigE cards,
but we are not coming close to pushing their limits, I'm still waiting for OC-3.

If you expect to push hundreds of megabits at peak through the multiport
card, then PCI-X will buy you some headroom. One caveat, many PCI-X
motherboards can only run one card at the full 133Mhz speed.
