NAK
The boot firmware for AMD/Nvidia chips is only run on PC, and the data is
only valid on some of them, in some cases, and not after a suspend/resume
cycle. You cannot rely on the BIOS (if any) loaded register values. Since
you've posted patches to clean up the drive side detect (when tweaked
with a couple of fixes), this hack won't be neccessary.
