PS2, Line 78: #if CONFIG(INTEL_TXT)
> I'm afraid I don't follow. The only redundant MSR writing I see is the one CB:59521 adds. That MSR needs to be written even if TXT is not supported.

Okay, just yesterday I was still convinced it shouldn't be written if CPU or chipset is not TXT capable, due to #GP it may cause (according to TXT BIOS spec).
