Ok.. so this may be a horribly basic question, but what does 'working
properly' look like -- I mean, how do I know if what I have is right or

Try calling show_page_walk(header), where header is the virtual address
returned by set_fixmap. You should see valid non-zero entries at both
levels of the pagetable.
How do I go about verifying the functionality of set_fixmap and the
subsequent set_pte_phys calls?
It would appear that it locates the header high in the memory space
(as it
should according to fixmap.h documentation), but there's nothing there
for
the subsequent call where it tries to map the table (at least this is
how
I understand it -- am I close?)
Yes, that's the problem. The mapping hasn't happened, or has happened
at the wrong place in the pagetables, or something like that.
