Well, I would have thought the same up until a week or so ago, but my 
conspiracy theory is that the 2.6.27-r7 gentoo kernel (don't know about the 
vanilla version) broke things.  In my case I couldn't get my sound card to 
work - alsa would error out not recognising my card.  I have been using 
oldconfig for years now, but also tried menuconfig just in case - of course 
it made no difference.  Filed a bug and it was suggested to me that I try 
building the alsa drivers as modules.  I tried it on for size and guess what, 
it worked!  I have not idea why as modules it worked, while built in the 
kernel it did not.
