Comment(by jnettlet):

 This is most likely a timing bug.  Previous XO kernels were patched with a
 kernel config option that told the kernel not to VT switch during a
 suspend/resume cycle.  This option has not been ported/activated to the
 3.0 arm kernels.

 We will either need to port this patch to our kernel, or have powerd
 freeze the DCON earlier during suspend resume.  If you are
 suspend/resuming manually using sysfs interfaces then the only way to
 cause the VT switch not to happen is by bringing in the kernel patch.
