Hello Brett;
Thanks a lot for the help on this issue.
The cure to the problem is... Instead of hand-rolling my own
ifcfg-eth0:x files, I used the GUI. Oddly enough this works. The only
real difference I can see from A to B was that the subinterface files
had a LOT more detail to them. More than I would have placed myself.
Another thing I did observe was when I would use the -route- command I
could see all sorts of default gateway entires. Weird. But now I see
one and only one. Which is more what I expected.
So much for being such a command-line bigot.

FWIW I have seen questions about this previously but have not sen any
answers. Perhaps it was you I don't know. try the archives at
marc.theaimsgroup.com. They archive the linux-net list ....
In fact take a look at this and see if it is pointing in the right
direction.
http://marc.theaimsgroup.com/?l=linux-net&m=104930510428818&w=2
IF no luck try the linux-net list. A couple of years ago a lot of the
coders working on the networking code were there.
