The standard ACPI dock driver can handle the hotplug bays and docks of
the ThinkPads just fine (including batteries) as of 2.6.27, and the
code in thinkpad-acpi for the dock and bay subdrivers is currently
broken anyway...
Userspace needs some love to support the two-stage ejection nicely,
but it is simple enough to do through udev rules (you don't even need
HAL) so this wouldn't justify fixing the dock and bay subdrivers,
either.
That leaves warm-swap bays (_EJ3) support for thinkpad-acpi, as well
as support for the weird dock of the model 570, but since such support
has never left the "experimental" stage, it is also not a strong
enough reason to find a way to fix this code.
Users of ThinkPads with warm-swap bays are urged to request that _EJ3
support be added to the regular ACPI dock driver, if such feature is
indeed useful for them.

Currently, the ThinkPad-ACPI bay and dock drivers are completely
broken, and cause a NULL pointer derreference in kernel mode (and,
therefore, an OOPS) when they try to issue events (i.e. on dock,
undock, bay ejection, etc).
OTOH, the standard ACPI dock driver can handle the hotplug bays and
docks of the ThinkPads just fine (including batteries) as of 2.6.27.
In fact, it does a much better job of it than thinkpad-acpi ever did.
It is just not worth the hassle to find a way to fix this crap without
breaking the (deprecated) thinkpad-acpi dock/bay ABI. This is old,
deprecated code that sees little testing or use.
As a quick fix suitable for -stable backports, mark the thinkpad-acpi
bay and dock subdrivers as BROKEN in Kconfig. The dead code will be
removed by a later patch.
This fixes bugzilla #13669, and should be applied to 2.6.27 and later.

The eee contains a logically (but not physically) hotpluggable PCIe slot.
Currently this is handled by adding or removing the PCI device in response
to rfkill events, but if a user has forced pciehp to bind to it (with the
force=1 argument) then both drivers will try to handle the event and
hilarity (in the form of oopses) will ensue. This can be avoided by having
eee-laptop register the slot as a hotplug slot. Only one of pciehp and
eee-laptop will successfully register this, avoiding the problem.

If we leave the camera disabled by default, userspace programs (e.g.
Skype, Cheese) leave the user out in the cold saying that the machine
"has no camera." Therefore, it's better to enable camera by default and
let people who really don't want it just disable the thing.
