Interesting analysis, thanks Takashi.

Ash, if you want me to help with debugging, I am usually on 
#mandriva-cooker and #pulseaudio on IRC (nick coling).

If I don't answer after a ping it means I'm not there!

Ash, if you think this would help, I can backport these two packages on 
Mandriva for the 2008.1 version but the driver will have to remain at 
1.0.16. (actually a current backport would get the 1.0.18rc2's).

And Takashi, do you age faster than most humans? 1.0.17 only went final 
few weeks ago!!! (although I accept there have been several good 
bugfixes since!!)
