Hi Len, sorry for using wrong emial address.

After your consultation I've found what caused my problems with broken 
hibernation resume on battery.
It's sony_laptop driver directly compiled in kernel. When it's compiled 
as module and reloaded every suspend cycle everything works as suspected.

I observed this problem first time in 2.6.25 kernel tree, but there were 
this problem only occassionaly present (2nd or 3th reboot it's resumed 
properly), but in 2.6.26 is permanenet resume problem.

What's next step? How can I help to solve this problem.

Thank you very much for help!

Best regards

Milan
