Some things that used to work in FC3 but don't in FC4: ACPI



The ACPI scripts for my Thinkpad don't work as they used to. For example, the script I use to turn off the backlight touches or removes a file to indicate whether the backlight is on or off. In FC4, the script is apparently not allowed to touch the file in either /etc/acpi/actions (where it used to) or even in /var/tmp (where I changed it to).

Also, radeontool appears to fail to detect the Radeon in lspci when run form the script, but it works fine when run from the command line as root.
The error is different from the one that usually occurs when running radeontool as non-root, which is "can't open /dev/mem Are you root?"
This error is "Radeon hardware not found in lspci output."


This issue also affects my suspend script, which is not permitted to write to /proc/acpi/sleep.

Any ideas what's going on here?

Thanks.
