Any recent UML is as valgrindable as the UML mentioned in the post you saw.

You need CONFIG_MODE_SKAS, !CONFIG_MODE_TT, and CONFIG_KERNEL_STACK_ORDER=3.

You also probably need some valgrind patches unless the stuff I and Jeremy
have done have been merged into valgrind CVS.

Once valgrind is working, you need to go through the false positives and
teach valgrind about how the kernel deals with memory allocation.  This is
the point at which I stopped.
