Given the support for SHA-1 and SHA-2 at 256 bit, it MIGHT be possible to write a kludge program to get it to mine Bitcoin - but it's not going to be competative with a Bitcoin ASIC unit.

Exactly. Cards like that are for secure end-to-end encryption/decryption of data, mainly banking transactions. For that use the keys are known to both parties at each end so they are not trying to 'crack' the hash, just process the data streams in/out.
AMD has some monster GPU's geared exactly for that use. Truth be told, 16nm chips for those specifically targeted at Banking and other Financial xfr usage is something like >50% of AMD's chips that they get from TSMC with the rest being for more mundane 'regular' GPU's and support memory chips.
