We probably can't change revision since Windows ACPI implementation

Patch needs to be tested with Windows guests starting with XP.

Works fine with XP as long as you don't use q35, but i guess that's unsupported by xp by default. 

 

related issue,
adding fields without changing major version to a corresponding
one doesn't look correct.

What do you suggest? saying we support 2.0a just because of introducing reset_reg is not really valid is it?
