So, I've written an AppleScript to do it all automatically. Point it at your ~/Library/Mail folder, and it will extract all the mbox files and put them in the correct hierarchy in a new folder. Simply drop these new mailboxes into your Thunderbird mail folder, and away you go. I've tested it in OS X 10.3.6 with Mail 1.3.9, and it seems to work fine, but I make no guarantees about other configurations.
[robg adds: I haven't tested this one, but I have looked at the script and it looks fine. I've also mirrored the AppleScript here on hints in case the original goes away.]
