Installed RHL6.2 on a UDB with a motherboard tulip ethernet interface and a tulip card in the machine. The conf.modules that results from the installation contains entries for eth0 and eth1 de4x5 and for an eth2 as old_tulip. Bill Nottingham suggests that this results from different module tables in the installer and in kudzu.
Changing component to kudzu (rather than installer).
this should be fixed in the current devel installer tree.
