Like others, Dell Vostro 1000 sets LINX, but never checks it.

TPOS and OSTB are also affected, but in the ASL they're referened
only with comparisons > 4, (NT or greater) so OSI(Linux) shouldn't
have any effect there either.

That leaves the return value of OSTP(), which I see invoked
in several places, but the return value is never used.

So I'll add this box to the OSI(Linux) NOP list.

BTW.

Where does 0x37E80F06 show up in the e820 map in dmesg?
I'm wondering why they put OSTY (TPOS) in a special place.
