rnd device is now almost mandatory, as we use ssh/openssh heavily
   	and openssh does not work without /dev/urandom.
   	GENERIC kernel for the following platform do not have rnd device
   	in the kernel config file:
   		bebox mvme68k newsmips sparc64
   
   	my question is:
   	- are there any specific reason for them to disable it?

not tested?

   	- does it make sense to add rnd device to them?

not until they are tested.


testing rnd on sparc64 is on my TODO list.
