build wince5.0 for LCD_TYPE_A70

Mathias Tantau
hello,
I'd like to build wince5.0 for my mini2440 with A70 LCD.
I am not able to switch from T35 to A70. I have changed the define in
options.h and rebuild it, but still the LCD only shows stripes.

Is it important to enable "Clean before Building"?

Any hints or suggestions?
Thanks in advance,
    Mathias Tantau
