X61 has the same problem. There are 2 video device object in ACPI namespace, \_SB.PCI0.VID (vgapci attached but brightness control doesn't work) and \_SB.PCI0.AGP.VID (has VBRC method but no driver attached because of wrong _ADR). The custom DSDT with the following patches and acpi_video(4) now can adjust brightness level :) http://people.freebsd.org/~iwasaki/acpi/tpx61.asl.diff If you want to make the custom DSDT, I can help you.
