It would be worth to test whether latest EC burst mode implementations
still walks this code path. If, you probably still have battery problems.

You could try latest 2.6.13-rcX patches and enable ec_burst=1 (with the
unfixed DSDT).
If this works, you will have to boot with this option a few kernels.
But it shouldn't be worth to look at any further as this will get default
sooner or later.

If you still have battery problems, you should open a bug at:
http://bugzilla.kernel.org
assign it to the ACPI component and take me into CC.

Thanks for digging into this,
