I just found this video - an eee running supercollider and jack!
http://www.mcld.co.uk/blog/blog.php?171

Also I found this benchmark:
http://novosche.blogspot.com/2007/12/eee-pc-benchmark-test-asus-eee-pc-4g.html

It's notated kind of inscrutably but I think it can be translated
thusly. Each cell shows average percentage of CPU to run the given
number of supercollider ugens / synth voices on the given platform.
So lower is better.

           128 ugens/ | 256 ugens/ | 384 ugens/ | 448 ugens/
            32 synths | 64 synths | 96 synths | 112 synths

----------------------+------------+-------------+--------------
powerbook 8% | 15% | 20% | 23%

pro intel 3.2% | 6.1% | 9% | 10.5%
1.84 GHz | | |
----------------------+------------+-------------+--------------

What this appears to show is that the EEE is roughly equivalent to a
powerbook G4 1.67 GHz, for this particular benchmark. And almost half
the speed of an intel macbook pro 1.84. That's not bad considering
the G4 *still* costs more on ebay than the EEE does new.

There's also a test of the number of synth voices at which the EEE and
the macbook pro each reach 66% CPU. If I read it right, the MBP can
do 800 voices (3200 ugens). The EEE can do 356 (1424 ugens).
