lap3 kernel: [282571.053156] thinkpad_acpi: unknown possible thermal
alarm or keyboard event received
lap3 kernel: [282571.053160] thinkpad_acpi: unhandled HKEY event 0x6040
lap3 kernel: [282571.053161] thinkpad_acpi: please report the
conditions when this event happened to ibm-acpi-devel@lists.sourceforge.net
(2) lsmod shows thinkpad_acpi is running.
I found in /lib/modules was
kernel/drivers/platform/x86/thinkpad_acpi.ko.gz
and possibly
kernel/drivers/acpi/acpi_pad.ko.gz
The first one seems to be version 0.24 but I cannot tell if its the
0.24-20110604 version or earlier - at least by poking at the .ko.
