Well, I guess the latest driver should work even without quirk because 
model=auto would be chosen as default.  In the older verison,
model=sony-assamd was chosen for Sony laptops, but it's disabled now.

If my guess is right, I'd apply a clean-up patch for 2.6.34, but no
need for a new addition of model=auto quirk entry for 2.6.33.
If not, please let me know.
