[Carl <crazy@wi.rr.com>]

Hello,

I have a Sony Viao SR-33, and the sonypi driver would not work until I 
applied this patch.

I don't know if this works for the general case or if this machine is a 
special case.  I hope people with other vaio models will check.

Also this machine suffers from the swap_apm issue, here is a patch.
