  I think I got the solution to the problem. I spent
some time pondering on the problem and a friend of
mine and I thought the solution to the problem is one
of two things. Either there was a redesign of the
syscons driver for the high resolution console or
perhaps the use of a different sound arhitechture. So,
I decided to take the easy route and try out the
4front OSS drivers for freebsd. Since then the problem
has been fixed. There is no longer any problem with
switching between Xorg and high resolution console.  I
suggest you try it.
