the problem was localized 
No more problems with switching to decrease the screen resolution in graphics modes 
(I just updated to tag =. 
I used to use its working version of freebsd consisting of many patches) 

but exists problem in switching graphic screen back to text mode on ttyv0
but only on ttyv0

I can not provide backtrace because the system is fully freezes

sequence that leads to the problem 
1) boot freebsd 
2) stay only on ttyv0
3) kldload vesa 
4) vidcontrol MODE_277 (800x600x32)
5) vidcontrol MODE_24  (80x24 text mode)

The system immediately freezes
switch to any of the consoles is an infinite beeeeeep

if you do the same but on another ttyvX (/dev/ttyv1 .../dev/ttyv9)
then there is no problem
