Dear all,

just committed a small patch that allows the VIDC registers to move
instead of being fixed at one place. The new bootloader puts the VIDC chip
initialy at a 1:1 mapping; the VIDC thus appears at VIDC_HW_BASE instead
of VIDC_BASE. By making the vidc dependent code to use the new variable
`vidc_base' its posible to easily shift the VIDC to the new place.

A better solution is needed and should be used with the wscons.

Cheers and enjoy !!
