eth0/eth1 swapped in Anaconda vs regular post-install boot

Description of problem:
This is with limbo2:
On a new Dell Inspiron 4150 with builtin 10/100 ethernet and wireless ethernet
ALT-F4 showed the wireless as eth0 and wired as eth1)
After the install finished, I booted into Limbo and the wired interface was eth0
and the wireless eth1!
The wired interface (using module 3c59x, lspci -v):
02:00.0 Ethernet controller: 3Com Corporation 3c905C-TX/TX-M [Tornado] (rev 78)
Subsystem: Dell Computer Corporation: Unknown device 012a
Flags: bus master, medium devsel, latency 32, IRQ 11
I/O ports at ec80 [size=128]
Memory at f8fffc00 (32-bit, non-prefetchable) [size=128]
Expansion ROM at f9000000 [disabled] [size=128K]
Capabilities: <available only to root>
The wireless interface (using wvlan_cs, cardctl ident):
product info: "Dell", "TrueMobile 1150 Series PC Card", "Version 01.01", ""
manfid: 0x0156, 0x0002
function: 6 (network)
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Commence installation of Limbo2
2.Make note of eth0/eth1 mappings to hardware
3.After install, boot into Limbo2 and note different mappings
Actual Results: In Anaconoda:
* eth0 == Wireless card
* eth1 == 3Com card
After the installation, they were swapped.
Expected Results: I would expect that Anaconda's detection of and presentation
of ethernet interfaces to be exactly the same as a regular, post-install boot.
How did you boot the installer? Using one bootnet.img/pcmcia.img or the CD?
Also, on a completely different desktop machine with a RealTek PCI card, and a Cisco
wireless Aironet PCI card, I observed the same behavior of eth0/eth1 swapping. That
machine was booted via the CD and used "askmethod" for an NFS install.
FWIW, I've observed this with Red Hat 7.3 (booting from CD) but never got a
chance to report it...
I did another clean install of Limbo2 on my lapotp. I booted from the cdrom,
and did a cdrom install (custom).
When it got the network configuration screen, I went out the kernel dmesg
screen (ALT-F4??) and verified that they were swapped compared to what post
This has to do with the different order we probe in a laptop display for network
hw, and on post-install where we bring up pcmcia network hw later.
We'll remove wvlan from the modules in the installer since we don't support it
*** Bug 70761 has been marked as a duplicate of this bug. ***
Please note that I have ALSO observed the behavior (see 2nd comment) on a
desktop PC that had two PCI network cards, one of them was a 802.11b PCI card.
wireless modules pulled from install disks
All wireless modules have indeed been removed. Closing out.
