I'm also running 2.4.2-2

I think IBM has done something to the hardware in the T23.
Mine shows this:

[root@chico /root]# lspci | egrep -i 'audio|ethernet'
00:1f.5 Multimedia audio controller: Intel Corporation: Unknown device 2485 (rev 01)
02:08.0 Ethernet controller: Intel Corporation: Unknown device 1031 (rev 41)

->  nutmeg(root): cat /etc/modules.conf
->  alias eth0 eepro100

I tried the same, and it failed to load the eepro100 driver.

Sep 27 08:03:02 chico insmod: /lib/modules/2.4.2-2/kernel/drivers/net/eepro100.o: init_module: No such device 
Sep 27 08:03:02 chico insmod: /lib/modules/2.4.2-2/kernel/drivers/net/eepro100.o: insmod eth0 failed 

Then I tried with the e100 driver:

[root@chico /root]# modprobe e100
Intel(R) PRO/100 Fast Ethernet Adapter - Loadable driver, ver 1.5.6

->  pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S \
->    >/dev/null 2>&1 || :
->  [...]

I put the same stuff in /etc/modules.conf, and it fails to load
it:

[root@chico /root]# modprobe snd-slot-0
/lib/modules/2.4.2-2/kernel/drivers/sound/cs46xx.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters
/lib/modules/2.4.2-2/kernel/drivers/sound/cs46xx.o: insmod /lib/modules/2.4.2-2/kernel/drivers/sound/cs46xx.o failed
/lib/modules/2.4.2-2/kernel/drivers/sound/cs46xx.o: insmod snd-slot-0 failed

I'm not normally this incompetent at getting stuff working, but
I honestly think IBM has tweaked the T23's hardware making it
hard for the linux drivers to recognize.  lspci -vv shows for
those two devices:

Thanks for all the help, guys!
