Latest -CURRENT/i386 could not start under VirutalBox 4.1.18 and 4.2 (Windows host): hangs up after atrtc0 detection

[Lev Serebryakov]

Hello, Freebsd-current.

  I've upgraded my FreeBSD-CURRENT Virtual machine, which I use to
 build router's NanoBSD image, to today's morning (MSK time, GMT+4)
 revision. Unfortunately, I cannot provide exact version, as sources
 are in this unbootable VM too :)

  Kernel is GENERIC.

  VBox configuration is rather stander: 2 CPUs, ICH9, 2GB of RAM.
  Host is Windows 7/64bit.

  Booting hangs after (new?) line:

atrtc0: <AT realtime clock> port 0x70-0x71 on acpi0
