Description of problem:
Booting the kernel-2.6.12-1.1447_FC4 on my Dell Inspiron 600m, the /proc/acpi/button directory is missing, which contains the lid and power button states. Booting the previous kernel-2.6.12-1.1398_FC4 returns things to normal.
The kernel messages look normal:
ACPI: AC Adapter [AC] (on-line)
Using generic hotkey driver
ACPI: Battery Slot [BAT0] (battery present)
ACPI: Battery Slot [BAT1] (battery absent)
ACPI: Lid Switch [LID]
ACPI: Power Button (CM) [PBTN]
ACPI: Sleep Button (CM) [SBTN]
ibm_acpi: Using generic hotkey driver
toshiba_acpi: Using generic hotkey driver
ACPI: Video Device [VID] (multi-head: yes rom: no post: no)
but the /proc/acpi/button directory is not created.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.boot new kernel
The 1450 kernel from updates-testing does not restore the /proc/acpi/button
directory when booted.
I have this as well.

Sorry. Just to be clear, I have this problem as well.
kernel 1456 just released also has this lack of a /proc/acpi/button directory.
this should be fixed in the 2.6.13-1.1524_FC4 just pushed to updates-testing

Yes it fixes it. My lid close script work again.
But brings up a couple of other problems. PCMCIA service has a problem and I
can't get the latest intel wireless driver to install. Do these need a new bug
[root@eyrie ~]# service pcmcia restart
Shutting down PCMCIA services: done.
Starting PCMCIA services: cardmgr: watching 1 socket
cardmgr: could not adjust resource: IO ports 0x3d3-0x3d3: Input/output error
Above definitions found. Comment out? [y], n y
sed: can't read /lib/modules/2.6.13-1.1524_FC4/build//build/.config: No such fil
e or directory
Please file a separate bug for the pcmcia problem.
The build//build looks funny, and looks like a bug in the ipw folks
configuration script. You may want to bring that up with them upstream.
The 1524 kernel does indeed restore the /proc/acpi/button. I did see the same
pcmcia error too.
Ok I added Bug 169268 as a kernel bug in regard to pcmcia. Hope that ok.
I look at the wireless problem a bit more. Something odd there though normal its
not a problem to get it working.
