This BIOS is one of those that has usable RAM both below and above its ACPI reserved regions. It is also one of the BIOSes that gets hung in SMM when the legacy USB buffers (in those ACPI reserved regions) are DMA protected. The work around is to disable legacy USB support. Meanwhile, I will be fixing tboot to not DMA protect these regions when it finds such a case (the current code will not DMA protect reserved regions as long as there is no RAM after them). This is a non-trivial fix, so it may take a little while.
