RE: ACPI very nearly working on Thinkpad 240x

From: Matthew Garrett [mailto:mjg59-1xO5oi07KQx4cg9Nei1l7Q@public.gmane.org] 

Having upgraded my BIOS to the latest available from IBM, I've very 
nearly got working ACPI.

1) S1 usually works correctly, but the backlight doesn't get switched 
off. Is there any trivial way of dealing with this?

2) S3 suspends and resumes. On resume, the backlight comes back on the
machine is responsive from the network. The keyboard and mouse don't
work, though - if I use modular input drivers, a rmmod i8042 
&& modprobe
i8042 brings things back to life. Switching on the Toshiba keyboard 
kicking code doesn't result in any change in behaviour. The 
symptoms are 
that no input results in an increase in interrupts until I reload the 
module. 

Given what I know about the state of the code, I am AMAZED you get even
this far. :) You are running into problems because your devices (mouse,
keyb, video) are not saving and restoring context properly on resume.
That code has yet to be written, although it's nice to know that
reinitializing seems to kind of work, too.
