As I told before (lines 4-6 in this mail), Felipe's patch to the
board-omap3beagle.c didn't help. Only way to make 2.6.31-rc6 booting
was to enable both of those config options + revert.

Yep. Actually I re-tested it now with make distclean first. Meaning
patch from this mail:

http://marc.info/?l=linux-usb&m=125041334606967&w=2

No sign of life.

Now reverting the e8e2ff462dd92693f29eb848f42d3eb720390d59

No sign of life.

Adding CONFIG_NOP_USB_XCEIV=y

Bingo!

Getting e8e2ff462dd92693f29eb848f42d3eb720390d59 back

Again, no sign of life.
