That is not true with modern hubs. You can get a 10/100 hub that works like
this: It has a 10Mbps segment and a separate 100Mbps segment. The hub has
an internal 2-port switch that connects both segments.

I have a 3COM 10/100 PCMCIA ethernet card for my Dell Inspiron laptop. It
works fine at 10MBps or 100Mbps. It uses the 3C575 module driver.

I think that mixed 10/100 Hubs are not that expensive. They are usually
around $200 for 16 ports.
