WAPBL disabled (w/o 'log') didn't help during my tests.

But: With that (KVA) hint I played with CUBIETRUCK's config and
modifying it like (== preserve original std.awin settings and limit
mem to 1 gb):

  #makeoptions   KERNEL_BASE_PHYS="0x80000000"
  #makeoptions   KERNEL_BASE_VIRT="0x80000000"
  options       MEMSIZE=1024

produced a working netbsd-7 cubietruck kernel for me (with the side
effect that 'bootargs' is no longer found / supported).

Does this help to localize the problem?

Markus.
