pulseaudio deeply unreliable (Fedora 10)

OK, I've had a google, and a bit of tinkering with config. files, and I'm
not really getting anywhere. PA was working OK for me in Fedora 8, but ever
since I upgraded F8 to F10, it's been a right PITA.
It'll either continually stutter (e.g., when playing music often 1-2
times each track) or hiccough and crash under CPU load (firefox loading can
kill it, for example).
Indeed, with my wife playing 'listen', CPU usage is PA itself is some
~20% or more. I have tried the 'tsched=0' hack, but that doesn't seem to
change anything (yes, I restarted PA).
I've seen PA quit itself due to "excessive CPU usage" (I've taken to
running it in an xterm to see when it's gone/what errors it's reporting). I
tried the max cpu flag I found in the PA daemon conf. file, but all *that*
did was just report 'Killed' when it died.
It just seems deeply unreliable. I can fairly reliably stuff it by
running realplay (listening to streamed radio) under padsp, and then
launching mplayer.
The only odd thing I see is some message about the ALSA and/or the kernel
reporting a range of 22.0 to 22.0 db or something, "indicating a bug in the
kernel driver".
So, what to try? Most googles of my symptoms lead to people who've had
enough and removed it. I did even see one report trying to blame nVidia's
drivers (which, regardless of veracity, is no excuse given that it was OK
before).
I'd *rather* get to the bottom of the problem(s), even if it's raising
bug reports and patching for now, but I'm really just fed up with the thing
now. If I can't get it going within a week, next weekend it's off the
machine for good.
