Persuading an Atheros wireless card to function in Lenny

[Lisi <lisi.reisz@gmail.com>]

I am trying to set up the wireless card in Lenny on an Acer Aspire One ZG5.  
Linpus has no problems, but the sooner I can wipe it off the hard drive the 
happier I shall be. :-(

I have wicd 1.6.2.2 (bzr -r463) installed.  I have installed the Atheros 5 
driver module and now get the following results from lshw and modprobe -l: 

Cronos:/home/lisi# lshw | grep ath
                configuration: broadcast=yes driver=ath5k_pci
latency=0 module=ath5k multicast=yes wireless=IEEE 802.11
Cronos:/home/lisi# modprobe -l | grep ath
/lib/modules/2.6.26-2-686/kernel/drivers/md/multipath.ko
/lib/modules/2.6.26-2-686/kernel/drivers/md/dm-multipath.ko
/lib/modules/2.6.26-2-686/kernel/drivers/net/wireless/ath5k/ath5k.ko
/lib/modules/2.6.26-2-686/net/ath_rate_onoe.ko
/lib/modules/2.6.26-2-686/net/ath_rate_sample.ko
/lib/modules/2.6.26-2-686/net/ath_rate_minstrel.ko
/lib/modules/2.6.26-2-686/net/ath_hal.ko
/lib/modules/2.6.26-2-686/net/ath_pci.ko
/lib/modules/2.6.26-2-686/net/ath_rate_amrr.ko
Cronos:/home/lisi#

But wireless still does not work.  I.e., I cannot get on the internet without 
a wired connection, and wicd reports: 

No wireless networks found.

I am at a loss where to go next. :-(  Googling, and a pointer from a friend to 
the relevant page on the Debian Wiki, got me this far, but are of no further 
assistance.

Any suggestions?  I really want to wipe that horrible* Linpus and rely on 
Debian.

Thanks,
Lisi
