as a simpler experiment, after the re-install, i left out wireless
configuration entirely and just verified that the wired eth0 came up
properly, which it did.

i then used s-c-n to remove both the device and hardware corresponding
to that, and it went away.  made sure all of the above was running,
rebooted, and wasn't told anything about an unconfigured ethernet
controller.  and here's where it gets amusing.

if i run s-c-n, there are no configured devices, but the Hardware tab
shows the Broadcom BCM4318 at (you guessed it) eth0.  and i see no way
to re-add that Marvell network controller, at least through s-c-n.
and if i check /etc/sysconfig/hwconf, there is an entry for the
Marvell controller, but it's now at eth1, whereas it used to be at
eth0.

so i'm just going to assume that, when i deleted the onboard
controller, that released the eth0 interface and the broadcom suddenly
snapped it up, at which point the onboard is now sitting at eth1.
i'm not going to pretend i understand what just happened here.  i'll
look at it some more.
