I've created a bugzilla entry[1] with all required files I think are needed? I'll try to extract the dsdt later and see if it has any compiler bugs and attach that later to the mentioned bug report. Also I will try acpi=noirq and see if that enables basic IRQ/USB support. In the meantime, anybody have any other thoughts as to what I can try?

This really looks like an interrupt routing issue for your hardware and a 64bit kernel. Nothing the USB developers can do about this, sorry. Try contacting the acpi developers by filing a bug at bugzilla.kernel.org and they can work on this. thanks, greg k-h
