well... i've stopped a bunch of services, and the idle memory usage is a 
little better, but still not what it was with gentoo.

interestingly, though, i'm getting better audio performance in a simple 
18-track ardour recording test than i was in gentoo. jack frames and 
buffers are at 64 and 2, and i'm getting NO xruns, even when starting 
and stopping other applications, resizing windows, etc. -- on my gentoo 
system, i could only barely run at 64/2 and would at least get xruns 
when starting and stopping ardour. furthermore, with this Planet setup, 
i'm doing it all as user rather than as root. now that is COOL!

and the install/tweak/etc. was done in a day. like i said before, more 
music time is what i want.

a BIG thankyou to fernando!

now, there is one remaining curiosity, which perhaps someone can help me 
sort out: my average load NEVER gets below 1.0, even with no 
applications running, and it is not solved by a reboot. the machine does 
not behave like a 1.0-loaded machine, so there's something strange going 
on here. i've read some references to processes in a D state causing 
this sort of thing, but there don't appear to be any of those, so i'm at 
a loss. any clues?

glad to be back on the Planet....
