do these have any pipes to unlock? do they use 12 or 16 pipelines?

no, they dun unlock.. and needlessly really.. the GS clocks so high that it covers its 4pp deficit against an ULTRA.
it came pre o/c to 485mhz 1.2ghz eff but ahd to tune it down to 450 mhz 1.1 cuz it wasnt working properly
scan are doing a 6800gt at a lower price than some of the 6800gs cards though
i got mine for 139 quid xfx 6800 gs lowest i saw was 160-170 for gt
I've heard that some AGP XFX 6800GS have pipes to unlock, but for pci-e version, forget. But overclock is enough to put this card having a 6800Ultra performance.
Unlucky yours wont clock as high.. But if you could (for some reason) get it to like 520ish/1250ish.. you're pretty much at around 440/1200 on Ultra..
The PCIe ones certainly don't unlock - they are a new fabrication at a smaller 110nm process (compared to 130nm for the GT). They are also natively PCIe unlike the GT which is AGP-PCIe bridged (not that that makes any difference).
But the smaller process means they clock very well bringing them up to the same performance as a GT.
Scan do stock GTs quite cheaply, especially on offer (I got mine for around 153) but I made that decision more on noise than performance - that and I don't want to overclock yet.
