The tg3 *is* awful.  Unfortunately, RHEL 3 Update 4 and RHEL 4 only ship
with the tg3 driver and it may not work with your Broadcom chip.  Check
out Red Hat's Bugzilla for all of the tg3 complaints.

That is not to say the Broadcom chip is bad.  Our experience with the
bcm5700 driver available directly from Broadcom has been very good.  For
this reason, Scyld Beowulf ships with the bcm5700 driver rather than the
tg3 driver.
