anyhow there's something that makes priority switching
somekind problmeatic, am I right? you've to decrease
priority 3 times before getting it set.

why you need to load speex codec library twice?

I see :/

Which one fails without the patch?

Are those plain vanilla kernel (fetched from kernel org) or are they provided by rmps
(yum)?

I'm not very familiar with Mandriva's world, though it seems to me that
coocker is the dev branch, isn't it? so maybe it could be something
in the cooker toolchain that makes things a little bit "unstable".

Any chance to test this on a different machine with a different
linux flavours? (cause I've never experienced such a bug both on
Debian (etch/4.0)and Ubuntu (>=7.04))
