Everything looks right DSDT wise, the EC offset for brightness didn't change.
I did a quick read through the linux-thinkpad ml archives and it seems that
this is a BIOS related problem. Older versions work, but current ones show
this problem. What BIOS and EC versions do you have installed?
Btw: acpi_video(4) should add a brightness sysctl for the lcd (judging from
your DSDT). How does this one behave? Does writing to the brightness sysctl
have any effect (acpi_ibm(4) and acpi_video(4))?

No objections here.
