Argh. Newer VAIOs are 'legacy free' iirc. Which means their APM support
is either nil, or close to it. In favour of the all new shiny ACPI
method of power management. 
Big problem being.. Linux ACPI support right now is 'flaky' at best.
The stuff merged in 2.4 currently is ok for most people, but there are
many systems out there which it is woefully inadequate at supporting.

The current out-of-tree work the Intel folks have done seems to be
making progress, but is in a flux of "works on this box, but not this
one is broke" right now. Expect better support to show up in 2.5, and
bits of it to get backported.

For complete ACPI power management support however (Including cool
tricks like suspend to ram/suspend to disk), it's likely that
we'll have to wait until 2.6 is out the door.

-ENOCLUE. He's talking bollocks.

*nod*, again with the improved ACPI idling, that should be stretched
somewhat.

Well, it's likely due to a Linux shortfalling that this issue occurs.
Does Windows last longer on battery ? If so, then this is due to them
having a more complete ACPI implementation than we do.
