It was relatively simple since the generic ac97 driver works fine and all I had to provide in addition to the probe and attach code were functions to read/write the ac97 registers of the m2e. If the kludges described in the comments of the Linux driver are the only way to get the Maestro2E to actually play audio, I'm not sure whether implementing a complete driver is worth the effort. If anyone is interested in the mixer code, I can check that it still works and make it available.
