Yes, I saw some dmi udev strings on Kay's machine and for the thinkpad
module dmi autoloading is much better.

Not in general, only if the driver provides additional functions and the
ACPI device does not appear on machines that need those additional
functions.
E.g. the asus driver AFAIK serves exactly the ACPI device it registers
for.
> Thus, I'd prefer if your patches did not make thinkpad-acpi autoload by HID.
It would not really hurt? At least thinkpad module is an acpi driver for
those two HIDs... But your are right, it's superfluous, here with
__mod_acpi_device_table symbol ripped out of thinkpad.ko.
Hmm, what do you think about splitting the Thinkpad driver into Hotkey,
PCI and rest? This one got a complicated beast...
Create __mod_acpi_device_table symbol for all acpi drivers.
modpost is going to use this one to create modules.alias
Hopefully thinkpad module still works.
IMO this one should get restructured and make use of acpi_bus_register_driver
and try to avoid to test for HIDs/CIDs for its own.
