Bug#521279: linux-2.6: bluetooth on/off button stopped working on Lenovo Thinkpad
Package: linux-2.6
Version: 2.6.29-1
Severity: normal

The button switching bluetooth on/off on Lenovo Thinkpad stopped working
after upgrading from 2.6.28-1-amd64 to 2.6.29-1-amd64.
According to Henrique de Moraes Holschuh (thinkpad_acpi maintainer),
this is because CONFIG_ACPI_PROC_EVENT is disabled. Quoting from a
discussion on the linux-thinkpad list:

Yes. Without CONFIG_ACPI_PROC_EVENT you will get hotkey events *ONLY*
through the thinkpad-acpi input device.
It has been that way for more than one year, now. It is warned everywhere
in the driver, there is even a backwards compatibility strategy in place,
which won't help you because acpid never got fixed to deal with netlink
events.

I do use the latest and greatest acpid:
bjorn@nemi:~$ apt-cache policy acpid
acpid:
Installed: 1.0.8-6
Candidate: 1.0.8-6
Version table:
*** 1.0.8-6 0
600 http://ftp.no.debian.org sid/main Packages
100 /var/lib/dpkg/status
1.0.8-1 0
700 http://ftp.no.debian.org lenny/main Packages
I believe acpid have to be fixed before CONFIG_ACPI_PROC_EVENT can be
disabled. Please enable it again for the next release.
