Yes, after realizing that possible lack of OMAP1510 McBSP1/3 / DSP 
support in the mainline tree could be the reason of my problem, I got 
back to omap tree. First I retried the new driver on commit 
90e758af52ba803cba233fabee81176d99589f09 and confirmed the prevoiusly 
seen hangup. I found that it was omap_mcbsp_request() never returning 
back from.

Then I retired the same on the commit 
d8376cc482b241701f7606c81ad578b90853e175 and got similiar hangup. Next, 
I moved mcbsp initialization to a boot time hook and finally heard a 
sound and got my first DMA interrupt!

So it seams I have finally managed to take all necessary steps back, and 
now I can go forward, I hope :).
