in start_kernel, bootldr gives us an entry point to the kernel (start of loaded .text):
copy first 15 words (vectors and their displacement constants) of kern text segment to
the beginning of physical memory.
this beautiful trick allows us to load kernel at anywhere we want and to let bootldr
be at 0x00000000 (yes, we are rewriting ourselfes, part of bootldr :).
