Hi Alexey,
Probably my e-mail comments before the patch mislead you...
If you download the kernel source and try to compile it, it won't work because
of the INITRAMFS pointing to a non-existing directory. (check log below)
That's why that option should be removed from the standard kernel.
Regards,
C.Palminha
