I've had this same problem for a couple weeks now. After a little digging I believe that the likely culprit was introduced in 2.6.19. From that kernel's changelog:

Right now I'm trying to build 2.6.20 without this specific check-in to see if this fixes things. FWIW, there appears to be another "bluetooth firmware" check-in, to 2.6.21-rc2, which may already fix the issue. I'll test that out next :)
