Hi Scott,
Please give more detail about the issue if you can.  I would really like
to understand how the changeset negatively impacted you in order to fix
the issue.

I have used this changeset on headless machines (so no keyboard or mouse
entropy) with both GENERIC kernel and a kernel without RANDOM.  For
kernel without RANDOM I even waited until I had a login prompt to load
the ko's in order to test having no /dev/random until fully multi-user.
