We've been through this before. http://marc.theaimsgroup.com/?l=linux-kernel&m=114067198323596&w=2 In addition, the SMI call used to change the backlight level *may* require (if configured by the sysadmin in BIOS), a password be entered. This begs for a common userspace app that can grok libsmbios and kernel interfaces both, and use the appropriate method on each, rather than just putting it all in the kernel.
