I didn't know NX needed PAE
The wider page table entries (PTE's) have the space for the NX bit
whereas the 32-bit wide entries don't.
The above only applies to 32bit x86 btw.
x86-64 runs PAE-alike PTEs by default, so it's always available there.

I mentioned HT in relation to NX, not to the SATA problem :-)
NX has no relationship with HT, so shouldn't make a difference.
