I guess this is actually only a partial summary as I haven't rebooted
yet, but one will be required.
After my original question several people referred to the System Admin
Guide Chapter 5, which I'd already referred to and couldn't find a clear
answer in reference to PCI devices. Plenty of info on SCSI however. Some
people actually sent the "hwmgr" commands that they'd used to move scsi
devices. And one reference to a dsfmgr command that I mentioned in my
update.
One person, Tim Brown actually gave me an answer that might work,
removing alt0, and alt2 then rebooting. To add some credibility to this
answer, after I sent the update indicating I was working with a PCI device,
I got the same answer from Dr. Blinn and Jan Mark Holzer. However, I didn't
think this would work in my case, because I have an alt1, that I want to
keep. And I'm not sure how the name algorithm works, so I was afraid
deleting alt0 and alt2 then rebooting, would still bring up the device as
alt2. I did not want to attempt deleting alt0, alt1, and alt2, then
rebooting. I was afraid the two cards might come back reversed.
The most complete answer and the one I used came from Phillip Brown who
gave me two options. The first was a repeat of the option outlined above.
The second option involved "telling" the name sub-system which name to use.
I had more confidence in that method so, after asking for a little
clarification on pci bus specification, I set it up. Now, I just have to
wait for a studies period so I can reboot and see if it works. Mr. Brown
also added a short explanation of why dsfmgr doesn't work in this case. I
included his answer in it entirety, although I believe, in the last line, he
meant "effective" not "affective". Unless he's really passionate about his
devices. ;-)

Hi, Jim:
Your goal, to fix your naming problem, is resolved by removing your alt
devices from the name sub-system and then rebooting.
To remove the entries from the name sub-system, use the following commands:
# hwmgr -remove name -entry alt2 <- and any others
Then reboot your system and that device should become alt0.
Or:
Instead of relying on the name sub-system to assign the name during boot
using its algorithm, you will "tell" the name sub-system what to use. You
will need to look at the entries for the alt devices using this command:
# hwmgr -show name
You will notice the slot assigned to alt2. This is where the device is
located. You'll use this slot number later.
Remove the alt2 entry from the name sub-system using this command:
# hwmgr -remove name -entry alt2
Now edit the alt0 entry to use the slot where the network device is now
located. Do this using this command:
# hwmgr -edit name -entry alt0 -slot xxx
(where xxx is the slot where the device is currently located)
Now reboot your system.
As you may notice, this is a dynamic modification of the name sub-system's
data - the names of the "hardware component", not the names of the "device
special files". So, dsfmgr doesn't work in cases like these.
Also, it requires a reboot (at this time) for the names to become affective
whichever option you use.
