Subject: [PATCH][2.5] fbcon.c complement_mask bug

When using a frame buffer console with a 512-character font, the mouse
pointer starts using the wrong complement_mask after a console reset.

This patch is against 2.5.71.  It fixes s_complement_mask so that it is
always a valid default value for complement_mask.
