I'm having basically the same problem since installing 2.6.27-11 on my Thinkpad X301. I haven't noticed any slowness in the power manager brightness meter, which goes up and down as normal, but it doesn't change the screen brightness at all.

Running

xrandr --output LVDS --set BACKLIGHT_CONTROL native

enables the Fn Up and Down keys to control the screen brightness (though it's flaky), so it's not a hardware issue.
