I've tested 8.10 alpha 5 live CD and the bug REMAINS. I've booted 3 times always with maximum brightness but after logging out the screen was darker. Also, when the monitor turns of after some idle time and you "wake" it, the brightness is lower.

I've noticed that in my 8.04, 2.6.24-19-generic (but not in 8.10 alpha 5 live CD) there is this line in dmesg output:

thinkpad_acpi: CMOS NVRAM (7) and EC (5) do not agree on display brightness level

Could this be of any help?
