Following some crypto conference news and common sense (even the US government is halting use of SHA1 signatures), this debian admin put together a good howto on upgrading and configuring your keys.
With very little deviation from the howto, I was able to get this going during some spare time today.
My windows experience was a little different though. The gpg.conf lives in win32's "Application Data\gnupg" folder, so my prefs didn't stick initially. And I had some trouble getting enigmail to prefer the new key and digest format, so I forced the extra options "-u KEYID --digest-algo SHA256".
