More information.  I substituted the Live FS CD for the intall CD to see
if I could use the binaries on it to help track down the problem.
However, I get 'Memory Fault' or 'Bus Error' whenever I attempt to run
any of the binaries, so I think it must be a driver bug of some sort.
Also, none of the directories below /cdrom/usr even show up, so there is
yet another problem.

The CD is a Sony CDU-33A 'Sun Moon Star' I picked up at WalMart.  (Hey,
this is Montana, WalMart is the *only* store who carries CD-ROMs in
stock).  I had to configure the kernel to look at port 0x340 instead of
the default at 0x230.  My CD can't even go there, so I jumpered up much
higher.  I'm going to try re-jumpering it higher again, but I'm don't
feel that it will help.
