Will try as soon as my bisect is done. Interestingly, both problems with 
this system - this one and http://lkml.org/lkml/2007/10/4/417 so far 
regress together - already somewhere after 23-rc6 and both USB and 
i2c-viapro still work... Might also be some configuration options that got 
lost while bisecting .22 - .23-rc9.
