Subject: [PATCH] fb: hide hardware cursor in graphics mode (Mach64)

From: Krzysztof Helt <krzysztof.h1@...pl>

A hardware cursor is left enabled in
the fb_set_par() which is called when
a new console is created. This is
inconsistent with software cursor's
behaviour.

Also, this makes a hardware cursor
always visible in the Xfbdev
(Xorg kdrive) server.

Finally, I acquired a Mach64GZ card and was able to 
solve this puzzle.

Risto, please test the patch.
