On many laptops (Compaq, HP) the touchpad is so slow responding
to reset that keyboard controller times out. The device is reset
nonetheless and works fine. Kill the "synaptics reset failed"
error; if device is not working then other parts of
synaptics_query_hardware() will fail anyway.

As the number of keymaps increases and is very unlikely to
reduce, this patch helps to reduce memory consumption by
declaring all keymaps as __initdata and copying right keymap
during DMI detection. On x86 this make the module size at

It turns out that the keymaps in the wistron driver are almost the
same, the main difference being some keys which may not exist and
leds which might not be present. Therefore it's possible to write
a generic keymap which would allow the use of an unknown keyboard
with little drawbacks. The user can select it specifying the parameter
"keymap=generic".

Acerhk supports already a lot of laptops. Lets import its database so
that everyone can benefit of the work of Olaf Tauber. Only the "tm_new"
laptops were imported. "tm_old" laptops could be possible but requires
more testing and probably only few laptops are still alive. "dritek"
laptops should probably be imported into a different driver. Also compress
the keymaps by fitting each entry on an int. Most of the dmi matching was
written based on google searches, so it's rather prone to errors. That's
why I'm asking people to confirm it works.
Support to generate switch input events was added as some laptops indicate
lid open/close through this interface.

Pete Zaitcev reports that with his touchpad, if he lifts the finger
and places it elsewhere, the pointer sometimes warps dramatically.
This happens because we don't store coordinates unless we detect a
touch so sometimes we have stale coordinates in queue (from where
the finger left the pad) and averaging makes cursor to jump across
the screen. The solution is to always store the latest coordinates.
