To the extent that this is an acpi-support problem, the fix is committed now and will be uploaded soon. However, with or without acpi-support, the kernel now synthesizes a keypress event for these buttons due to the mask set in /sys/devices/platform/thinkpad_acpi/hotkey_mask. The setting of this mask is currently done in the hotkey-setup package; I'm not sure whether we should consider this current mask setting wrong, but that's the next package in the chain, so opening a task there.
