Nah; my system is also 640MB.  I haven't had as much trouble with music
skipping - the main test case for me is Mozilla.  I guess I should start
playing music and trying to reproduce this.  Mozilla is clearly a fairly
substantial contributor to my problems.

I believe that to be the case.

Okay, let's start comparing widgets.

sysctl.conf says:

Kernel tuning... anything magic in your kernel?  I don't think I have
any.  My kernel is built with
	options DUMMY_NOPS
which I understand should *improve* performance, but I may be correct.

Hmm.  I have DEBUG and DIAGNOSTIC compiled in.  Perhaps they're more
expensive than I thought?
