It seems like networkmanager runs iwlist or does some equivalent on a
frequent basis (even if it already has a wifi connection), and uses
quite a bit of CPU doing it. I no longer need to worry about this
since switching to debian, where the /etc/network/interfaces config
file plus the ifup/ifdown commands that reference that configuration
have served me just fine.
I have an EEE 1000 and I use it constantly with Debian, and have performed with
it a good half-dozen times now, and rehearsed and practiced on it many more.. I'm
very happy with Debian-EEE. I created packages for the RT kernel and relevant
drivers for it, and uploaded them here in case anyone wants them:

I dislike the Network Manager intensely, so I turned it off. I just type "sudo
iwlist ra0 scan" when I need to find what's out there. Nowadays I just use a
Sierra Wireless USB adapter with the Sprint PCS network instead, and very rarely
fire up the wifi anyway.

Thanks everybody for your help and suggestions.
I ended up going with Debian as that's what I am familiar with.
http://wiki.debian.org/DebianEeePC
Being a bit lazy (like oz/zi) I grabbed the 2.6.29-rc6-rt3 realtime kernel I have been
using on a 32bit partition on the amd64 box and that seems to work OK on the Eee. I wanted
the .29 series coz it's got the wireless module for the 901 in the kernel.
I installed Qjackctl and was a bit puzzled why JACK would not start until I realised that
Qjackctl does not install jackd automatically as a dependency. I installed jackd and now
it works.
Plugged in my Korg padKONTROL and CME UF5 keyboard controller via USB, hooked them up to
AMSynth in Qjackctl's Connections pane and I was up and running. The little Eee sits
up on top of the UF5 perfectly, like they were designed together.
It is very early days and I have to sort out a few things - eg. sound only coming out RH
side - but there is a lot of help both here, on the DebianEee site, on the Pianotek forum,
on Ken's blog, and other places and I'm grateful for that.
Thanks again!
Norv

Debian testing here, 2.6.29.5-rt22, ASUS Mobo (don't remember exatly
what model... I am at work now)
Optimizing the kernel? ... it depends from your hardware but, apart
from binary size, I can not really say if turning off wireless stuffs
from kernel config could improve RT performances. I am sure somebody
else can comment bettere on this.
I'm slowly turning my wife's old laptop (2.8GHz Celeron, 768MB RAM,
saddled with older Intel chipset) into a synthesizer/effects box. It
currently has Ubuntu Studio on it. While I have the wireless antenna
turned off (we have no wireless network around here), I've never
disabled the wifi kernel modules or drivers. And it runs along quite
happily at latencies between 5-10 msec using an external USB audio
interface ...
I seem to recall that the problem with wifi wasn't the presence of the
drivers, it was the fact that the system was incessantly trying to make
a wifi connection. Maybe that's something Network Manager does that
doing your networking using command line stuff doesn't?
