tip: i810 + vga-out + mouse pointer

Trouble: when i connect vga-out (switching ctrl+F6) the mouse pointer disappear some times (randomly).

Solution: adding this line to xorg.conf ( video device) the trouble was solved:
Option "SWCursor" "true"

explanation: Apparently when switch resolutions that they aren't the standard (wildscreen's resolutions), hardware cursor don't work correctly and cause this problem, so this option disable the hardware cursor and let my work with software cursor.
