Ohad, could you tell a bit more about your issue?

Sure, feel free to ask.

Does this 'large region'
is a device private region (declared with dma_declare_contiguous())

Yes, it is.

See omap_rproc_reserve_cma() in:

http://git.kernel.org/?p=linux/kernel/git/ohad/remoteproc.git;a=commitdiff;h=dab6a2584550a6297

There have been some vmalloc layout changes merged to v3.3-rc1. Please check
if the hardcoded OMAP_RPROC_CMA_BASE+CONFIG_OMAP_DUCATI_CMA_SIZE fits into kernel
low-memory. Some hints you can find after the "Virtual kernel memory layout:" 
message during boot and using "cat /proc/iomem".
