Hi Robin,
Here's what I got...
- Installed eeebuntu rc2 - http://eeebuntu.org
- Installed 2.6.24-19-rt kernel
- Ditch the freq modules
> for freq_mod in `lsmod | cut -d" " -f1 | grep freq`; do sudo rmmod
> $freq_mod; done
>
- Use rryans's branch to get the faster wave form
- Apply real-time permissioning to audio group

The net result is I can run Mixxx on the eeePC pretty decently @ 16 ms with
ALSA.
It would run smoother still with EQs enabled and jackd, but eventually jackd
segfaults and kills kernel too... :(
Cheers,

Bonus: Bash script to rebuild wifi and webcam support on eeebuntu after a
kernel update...
