Speaking of which I now have a reliable repro for "d0:v0 unhandled page
fault (ec=0000)" early-boot crash.

Go in to a file in the kernel and add the following:

unsigned char foo_bar_baz_furfuu_quux[1<<20];

Turns out that it is related to kernel image size after all. The crash
happens regardless of which section the big variable gets linked in to
(ie. text or data).
