As I understand the issues, you have the right to reverse engineer hardware except where the DMCA applies. I don't see any way a patent or similar could prevent you from publishing results. Again, the DMCA might.

There are a few things that might be able to impose such a restriction on you. If none of these apply, I think you should be okay: Any EULA, shrink-wrap, or click-through type agreement that might apply to the software (whether the driver, OS, analyzer, or whatever). Also, any actual agreement you entered into.

Patents don't provide any ability to keep things secret. Copyright doesn't apply to a creative work you made yourself, even if it describes the creative work of another in *functional* detail.

IANAL, and I might have missed something. IMO, the DMCA or a driver EULA are the only things you really need to worry about. It's hard to see how the DMCA would apply if we're not talking about some kind of content protection scheme.
