Add some extra sanity checking and checks to printf format specifiers.
Try even harder to find a console before giving up.
Make devices with registers into the KVA region work reliably.
Turn on VM_KMEM_SIZE_SCALE on 32-bit as well as 64-bit PowerPC.
Return NOKEY instead of 0 if there are no more key presses queued.
