Bug#288522: debian-installer: more information
Package: debian-installer
Followup-For: Bug #288522
As requested, I spent some time researching the issue. If examine dmesg
when booting into the 2.6 kernel, I see the following pertinent
information about network initialization:
ieee1394: Initialized config rom entry `ip1394'

As can be seen, it appears that the 1394 firewire interface is
enumerated as eth1, and my wlan is enumerated as eth2. If I examine
dmesg when booting the 2.4 kernel, I see that the 1394 firewire device
is not enumerated as an interface and my wlan is enumerated as eth1,
which is the same configuration that the debian-installer set up during
its first boot seqeuence:

Notice above that the 1394 device is not given an interface name.
Ok, so now that I know that my wlan is called eth2 during a 2.6 kernel
boot, all I needed to do was duplicate the settings for eth1 in
/etc/network/interfaces (which includes ssid and wep settings) as eth2.
Now, wireless networking works flawlessly for both the 2.4 and 2.6 kernels.
So I think that this all boils down to the fact that during the 2.6
kernel boot process, the system decides to enumerate firewire devices as
interfaces whereas during a 2.4 kernel boot the system does not.
