Straight binary kernels have tighter requirements, because they're _not_
entirely position independent.  Firstly, with dynamic physical offset,
they calculate that based on their position in physical space when
they're first called.

So, with a PAGE_OFFSET of 0xc0000000 and a link address of 0xc0008000,
a binary kernel image better be placed at 0xXXXX8000, and it _will_
assume that RAM starts 32KiB below itself.  And yes, the 32KiB offset
applies as the kernel uses TEXTADDR-16KiB to store the initial page
tables.
