PATCH 1/1 sonypi and byteswapped apm minutes.

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.
