that does the trick :-)
now we(most likely you as the brain)  probably should find a smarter
solution
smth like :

sugestions
(order IMO easy to implemet->hard to implement & nice)

1.)
startx --- ./usr/X11R6/bin/X... -vt_shift 0 ( or omit) vt7
startx --- ./usr/X11R6/bin/X... -vt_shift 16 vt17
startx --- ./usr/X11R6/bin/X... -vt_shift 32 vt33

2.)
Option "SingleCard" "true"
Option "VtShift"       "0"  /* or omit */
.....
Option "SingleCard" "true"
Option "VtShift"       "16"
.....
Option "SingleCard" "true"
Option "VtShift"       "32"
.....

3.)
may be add /proc/bus/console/xx/vc_first
and teach XFree to use it

while on adding stuff :-)
don't you think it would be usefull to expose vc_first,vc_last or vc_range 
in proc ?

4.)
start buging the XFree developers ?
may be too early, when the F... will Linus leave 2.6 to Andrew
and open 2.7 , and when ruby will be merged ?

both heads with driver "fbdev" is the same ->
X(head 1)  switch to VC & back -> Problem
-->> X(head 1) displayed on both heads
++>> VT switch on head 2 fixes it 

X(head 2)  switch to VC & back -> everything OK
++>> X(head 1) displayed on head 1  
++>> X(head 2) displayed on head 2
 
order of starting X is not important
---------------------------------------------

there is one more ?issue? with the second head
the cursor never blinks, it stays all the time turned on
a bit strange but everything else is OK

best,
