hey Klavian,

your almost setting your kernel up like you plan on doing audio work.

It's sounds like your problem, wasn't even Wine related, and that you
were having kernel and priority issues.
The power consumption is a bit wierd, as i do not experience that,
from those patch sets.

I use the BFS patchset, as it is included in Zen-kernel
(www.zen-kernel.org).   you should check it out. you can also setup
"schedtools" with SCHED_ISO applied to X by default, right in the
.config (menuconfig).   You may also find that certain applications
will benefit from using SCHED_ISO.  Examples would be
Jack-audio-connection-kit, I use it with "mypaint" and any Wine
application that seems to not be keeping up.

it keeps everything nice and smooth.
