I have never really tried finding out WTF in the firmware causes this, but: 1. The backlight-change firmware runs in SMM. 2. The calls happen in ACPI DSDT 3. The SMM code DOES take care of the CMOS NVRAM You could well find something interesting if you dissect what happens to the NVRAM. Maybe changing it before/after/during the ACPI call has something to do with it, etc. -- "One disk to rule them all, One disk to find them. One disk to bring them all and in the darkness grind them.
