keep yaird out of testing

[maximilian attems <max@stro.at>]

#457177 summarizes the known grumblings of yaird failures.
current state is no fun and thus i may ask to keep 
it away from testing users.

d-kernel will keep yaird install possibility for 2.6.24 
even if it highly likely don't grok it, but we are considering
to remove it beyond that release.
don't want even to start think about it's pata support.

thanks
