cg14 frambuffer bug in 2.2.19 (and probably 2.4.x as well)

Hi guys,

I have a patch here that fixes an annoying bug in the cg14 framebuffer
driver on sparc32 platforms. The bug is when it never switches off the
cursor before going into X11 mode, so you get an 'orrible cursor
overlaying whatever you've got on the screen, in the same position as the
consoles. Switching to any console and back to the X11 display, the cursor
overlays the last position the cursor was in on the console. On
investigating, discovered that the cg14 framebuffer doesn't switch off the
cursor!

Here's the patch:

Hey, they *are* out to get you, but it's nothing personal.
