Good point, there probably is:
- The GM45 datasheet has ways to determine that, so on nehalem there is
  probably something similar.
- Flashrom also has ways to determine that.
- GM45 RAM init probably also have ways to determine if HECI is
  present, I didn't check yet.

Note that I don't have nehalem hardware to test with, and may not have
the time to work in a full solution.
