OK Elmer, I guess I'll claim the yacht!
I just got a new iMac Core i7 (SSD + HDD) that came pre-loaded with Lion. I used migration assistant to migrate over from my MacBook Pro (running Snow Leopard) to my new iMac. Not surprisingly, the Graphic Patchbay wouldn't connect when logging into Lion the normal way (which is 64-bit). GP will actually launch, but all of the choices are grayed out (un-selectable). Auto Connector won't even launch.
Anyway, I thought I'd try logging in in 32-bit mode to see if Elmer's speculation that mLan should work in 32-bit was correct. I tried restarting while holding down the "3" and "2" keys simultaneously on my wireless keyboard, but that didn't work (I always ended up in 64-bit mode). However, I tried the same thing again after plugging in an old WIRED keyboard and Shazam, 32-bits-ville! (When restarting, by the time the computer connects with a wireless (BlueTooth) keyboard, it's already to late to be holding down the "3" and "2" keys. Apparently, you must use a wired keyboard with a desktop Mac to boot into 32-bit Lion.)
So now in 32-bit mode, I connected my 01x to my iMac with a FW400-FW800 cable, turned on the 01x, launched GP, and it connected to my 01x! I tried iTunes, Logic, and MainStage and I could get audio in and out of my 01x and control Logic (move a fader on the 01x and same fader moves in Logic and vice versa). Woo Hoo!
I didn't do any real extensive testing, but it looks like everything should work in Lion as long as you boot into 32-bit mode!
Elmer is right (as always).
So, about that yacht...
