C. Boot options
The framebuffer console has several, largely unknown, boot
options
that can change its behavior.
<snip>
4. fbcon=rotate:<n>
This option changes the orientation angle of the console
display. The
value 'n' accepts the following:
0 - normal orientation (0 degree)
1 - clockwise orientation (90 degrees)
2 - upside down orientation (180 degrees)
3 - counterclockwise orientation (270 degrees)
The angle can be changed anytime afterwards by 'echoing' the
same
numbers to any one of the 2 attributes found in
/sys/class/graphics/fbcon
rotate - rotate the display of the active console
rotate_all - rotate the display of all consoles
Console rotation will only become available if Console Rotation
Support is compiled in your kernel.
NOTE: This is purely console rotation. Any other applications
that
use the framebuffer will remain at their 'normal'orientation.
Actually, the underlying fb driver is totally ignorant of
console
rotation.

According to http://ubuntuforums.org/showthread.php?t=360596 you can
add;
Option "Rotate" "CCW"
to the device section in xorg.conf.
Also, this *might* help
