Well, partial success.
I tried a 8139too card in the machine, and it worked without this hang.
I attempted to upgrade the kernel to the newest rh kernel, but the CDROM
will not read the CD-RW I burnt with the data on it. :( I installed from
CD, so I know the drive works. The CD-RW works in another machine. WIERD.
I tried the FA-310 card in the box that the 8139too card came out of,
and it hung the machine at first, but after booting into the new RH
kernel, it works seemingly ok.
Here is a related RH bugzilla link:

Hmm, maybe I'm not going crazy, and it really is a kernel driver issue.
