I believe the BIOS is buggy with that respect (not sure why the DSDT compiler freaks out but that might be a different issue). I manually looked up those values in the DSDT you provided, so based on that data the kernel takes the right steps. The question is whether the new BIOS fixes this or whether this needs a general exemption for being a special (known broken) machine. It seemed to have worked in the past. There certainly can be a solution to Jaunty (though it needs a kernel change), but that cannot be the sole solution as it will likely break with every newer kernel. I cannot exactly say how to proceed from here. But I try to ask around. Meanwhile to complete the data gathered here, could you add the output of "sudo lspci -vvvnn" to the bug report please?
