tyan k8e - both tigon3 and nvidia ethernet nonfunctional

[Wolfgang S. Rupprecht]

I just installed FC4 on a tyan k8e (nforce4 w. tigon-3 ethernet).  Not
only is the nvidia-MAC/marvell 88E1111-CAA PHY inoperative, but the
Broadcom BCM5721 (tigon3) is too.  They show up as eth0 and eth1 but
neither show any rx or tx packets in ifconfig.

A linksys EG1032 (syskonnect) pci card works temporary work around,
but it is kind of sad that this mobo has two on-board ethernets and
neither work with the default config.  Is there some standard work
around I should try to get the either of the ethernets working?
