Digging deeper I am seeing numerous page faults while loading resources, such as:

Most of the resource loading pagefaults occur silently unless you have KDB set
to trap them, but the fatal page fault occurs when you move the mouse in the
second stage installer, causing the mouse cursor to be drawn. That is when you
will see the first and fatal page fault.  Also of note, the Messagebox you get
when you do not fill in your name in the second stage installer is missing it's
icons, replaced with what appears to be the system default icons.  Conferring
with Alex, this probably means resource loading in general is affected.
