So interestingly, this is not a new issue. If you pass any type of setup
data, OVMF appears to be doing something unusual and passing 0xffffffff
for all the entries, rather than the actual data. The reason this isn't
new is: try passing `-dtb any/dtb/at/all/from/anywhere` and you get the
same page fault, on all QEMU versions. The thing that passes the DTB is
the thing that passes the RNG seed. Same mechanism, same bug.

I'm looking into it...
