Subject: pm2fb: panning and hardware cursor fixes
From: Krzysztof Helt <krzysztof.h1@xxxxx>
This patch:
- disallows setting of virtual height above 2048 as it does
not work for accelerated copyarea and imageblit
- fixes blinking of pm2v cursor by pushing cursor outside
the display (x=2047)
- fixes hardware cursor position on Permedia 2 chips with
panning enabled
- enables hardware cursor by default
