First, welcome aboard. :)
I accept your remark. Even though, since it was explicitly mentioned in the Errata, it was my responsibility to read about it before the installation, and surely before I wrote about it here. Since the issue is known to Mandriva and to the community, there is no point in leaving this topic open. The members sometimes review all the topics and search for the unsolved ones, and I didn't see it necessary to waste their time if the issue is known.
Regarding your other questions - unfortunately, I don't know if there is a patch or when it is expected to hit Mandriva's mirrors. I decided to roll back to 2009.0, which is much more stable for me.
