Have a look at linux/Documentation/fb/fbcon.txt

,----
| 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.

So one solution is to create a startup script which change
/sys/class/graphics/fbcon or add a boot parameter.
