I see these messages already with 2.6.27.3:

  # grep non-query /var/log/dmesg
  [    0.205977] ACPI: EC: non-query interrupt received, switching to interrupt mode

There are 9 more occurrences in the current ring buffer:
  # dmesg |grep non-query | wc -l
  9

Each one happens right after waking from S3 sleep, for example:

  [70168.288590] CPU1 is up
  [70168.288594] ACPI: Waking up from system sleep state S3
  [70169.624254] ACPI: EC: non-query interrupt received, switching to interrupt mode

The setup is a TP T60 w/ Intel graphics, wireless (i.e. no taint),
Debian unstable, but with vanilla kernel 2.6.27.3.
