Found it. I found this once before, but couldn't find it when I looked,
but it was still there :-/

Anyway, here's the commit that prevents my box from booting:

commit 41e95d95208c62d4b0fbcee5f16d93e23ca32984
Author: Ingo Molnar <mingo@elte.hu>
Date:   Thu Sep 17 23:12:20 2009 +0200

    <not-for-merge> Disable DEVTMPFS_MOUNT for now


It seems that this box requires DEVTMPFS_MOUNT to be set in order to
boot.
