After 3 1/2 years of reading the digest, I finally got fed up with the same issue this weekend. I hacked up a quick perl script to split up the digests into their own mailboxes (by forum) and de-html-ify the messages. Reading with mutt gives me nice threads, etc.
You can get the script

I drive the script from my mda; here's (the relevant part of) my ~/.procmailrc:

I've only just made this usable so I'll probably be adding features and fixing bugs in the near future, but feel free to use it as a base for your own work.
