any info on this? I got a T430 from my work. I am afraid I will have to do
the manual calls like on my personal X220.

I am using T430 with FreeBSD 9.1 amd64. And I want to say that this laptop is 
a best choice to install FreeeBSD on it. Brightess control work just fine. But 
it work with nvidia card. I didnt tested integrated Intel adapter. BIOS 
settings allows me to select primary adapter for video output.  

Message appears each time when brightness control key pressed:
CPU0: local APIC error 0x80

These errors just informational. And I dont give it any attention.

Suspend/resume also work without any problems.

I will test intel adapter and let you know if needed.
