So, you’ve always been annoyed by the fact that you have to load all those
laptop, i2c, hwmon, hdaps Linux kernel modules manually without having spiffy
udev doing that work for you automagically? No more! I just sent a patch to LKML which adds DMI/SMBIOS-based
module autoloading to the Linux kernel.

Hopefully this patch will be integrated into Linus’ kernel shortly. As
soon as that happens udev will automatically recognize your laptop/mainboard
model and load the relevant modules.

Module maintainers, please add MODULE_ALIAS lines to your kernel
modules to make sure that they are autoloaded using this new mechanism, as soon
as it gets commited in Linus’ kernel.

For a fully automatically configured system only ACPI-DSDT-based module
autoloading is missing. I.e. load the “battery” module only when an ACPI
battery is actually around.
