Well, I have an Emu 1212M, which I guess is the closest you're going to 
get. They use the same driver, though, as far as I know, so I might be 
able to answer your questions.

In general, how does the 1212M play with ALSA? It does well enough if 
all you need is the audio ins and outs. As far as I know, the outputs 
are still limited to 16 bits (the inputs can run at 24 bit) because the 
driver is not finished yet. I've also been unable to get MIDI in working 
(in Ubuntu Studio 64 Hardy Heron), even though I can see the MIDI in 
ports from kjackctl. I need to flip back over to Windows and test MIDI 
there (where it was working at one time) to make sure it's not a 
hardware issue.

I don't know if the guy working on the driver still is, or what progress 
he has made since I last checked up on it.

Another issue I run into is the lack of support in the driver for 
automatically resampling output (I run the clock at 44.1khz). I have to 
make sure the audio software I use is able to support its own output 
resampling. This is less big of a deal, as I plan to do all of my 
production at 44.1, but I do have the odd mp3 encoded at 48khz for 
whatever odd reason. Aqualung has solved this for me, though.

If you have any more specific questions, feel free to fire them off at 
me, and I'll do the best I can to answer them.
