Hi,
if you check your CPUID, does it support FIDVID?
If yes, then there is another problem. Perhaps you are hit by some errata which says first is needed not HT reset (LDTSTOP) but PCI reset. I don't have a code at my hand right now, but is HT reset stuff done _before_ the fidvid?
I think that all the revf/g processors support fidvid even if it can't be changed. The S1G1 socket means revf and above and checking for support really isn't needed. I think it is safe for a platform to make some assumptions like that.
Have you narrowed the reset to the fidvid code? After fidvid setup there should be a ht reset as Rudolf noted. You can skip fidvid setup for now. It just means that the processor will run at min frequency.
