Actually I do not have a deep knowledge of the chip and the device driver.

But I've made a test on similar hardware:
 1) CPU VIA EDEN 533MHz, 256 MB RAM, 2 Realtek;
 2) CPU VIA EDEN 600MHz, 256 MB RAM, 2 Via Rhine (a VT6102 Rhine II, and
VT6105 Rhine III chip);

The same O.S. was used: FreeBSD 4.9 (on NetBSD 1.6.1, the Rhine III was
not usable); the box was configured as a bridge between two LAN.

Result:
 - on low/medium LAN traffic no difference noticeable;
 - on hight LAN traffic (several download between the 2 LAN) the Via Rhine
cards show to me a delay in the interactive sessions (ex. terminal
server, ssh);

So it seems to me even the infamous realtek cards perform better than Via
Rhine.
