Yes, those should comply to the ACPI smart battery section of the 
specification.  Unfortunately, it's not a simple matter to write a 
driver to that interface.  Linux is still working on this as well.  I 
don't have the time to write the driver but if someone with the ability 
wants to do the effort, I'd be happy to give pointers for how to 
interface with our SMBUS subsystem.
