Aha, then we should not touch it h2200_lcd.c. I have fixed this and
commited to CVS. This could be the cause of the black screen you're
getting, Alain.

One more question, then: if I understand correctly,
GPIO_NR_H2200_LCD_RESET_N binds to POR# pin of MediaQ, which is active
low (that's why it is _N). Why it is needed? To say so, why we may want
to reset the MediaQ when we can power off it and then power on with the
same result? :)
