user1878: Deterministic keys are based on the sha256 hashing function.  As described in the link below deterministic keys use the same hashing function.

Is it possible for an FPGA to be repurposed to quickly find the hashes for poorly chosen keys?

user13413: An FPGA can do anything, by definition (Field Programmable Gate Array) they can run any bitstream you care to write for a specific task. The BIP0032 wallets you're thinking of however are 128bit keys with significant key stretching, so not a chance in hell will you ever crack one. That's by design.
