Backlight keys in Lenovo Thinkpads

I'm fighting with backlight problem in my X61s thinkpad. As far as I
understand the source of the problem is that the keys are not pure 
hardware keys any more as they were in IBM thinkpads.

The keys are working during boot and also in DragonFly if I disable ACPI. 
If ACPI is loaded, the backlight keys don't work any more.

So, any pointers regarding issue? Note, that I'm not interested in 
workarounds, I have plenty of them ;). I already did quick hackish port 
of the acpi_video driver from FreeBSD, but although it gives me ability 
to control backlight via sysctl's, it doesn't make keys work.
