Hmm, strange: I double-checked my Thinkpad update tool about a few hours
ago but it didn't show up a BIOS update. Although I remember having seen
one some time ago. I'll check this tomorrow.

Yep, that works. By the way, just looking at
/sys/class/backlight/thinkpad_screen/actual_brightness, I wonder if that
shouldn't be called "current_brightness" instead? (No idea if you mean
the acutal or the current brightness, I'm just asking because this is a
very common "false friend" in germany ;-).)

Do you have an idea about the delay between pressing the button and the
display finally adjusting brightness? Setting via sysfs causes the
brightness to change immediately.

I'll see if I can get a 2.11 tomorrow.

tpb works fine, but I tested it without tpb.
