I tried to set breakpoint on `sha256_block_data_order` to see whether the expected path is taken, but realized that `_gnutls_x86_cpuid_s` is cleared at that point, because of the re-detection in `register_x86_padlock_crypto`. Let me adjust it before merging: after fixing this SHA2 will become 4 times faster on my system :-)
