This started to happen after the second ACPI merge which was for 2.6.23-rc2.

It appeared after new Embedded Controller code was merged into ACPI. It 
might as well be just a debug message or a remainder to add support for 
new queries (whatever these are), but I do not know. The message itself 
seems harmless.

This _is_ a debug message. EC asks us to perform query which was never defined in DSDT.
Previously I thought it would be rare error report, but now it seems that every machine
has at least one unregistered query... It is not a functional regression, as we just 
ignored errors from query execution before.

Len already has a patch to remove this printk.
