Mouse pointer does not move after switch to kernel console and back

[Martin Sucha]

Background:

• I compiled HelenOS with framebuffer settings for 1280x800
• When booting, the mode switch probably failed
• I don't see the HelenOS logo and terminal buttons

How to reproduce:

• Move mouse, the pointer shows up and can be moved
• Press F12 to switch to kernel console
• Type continue
• The mouse pointer shows up after a portion of a second at the spot it was before the switch to kernel console
• The mouse pointer does not move, however.

Using PS/2 or USB mouse does not make a difference.

Also note that graphical console is used as the pointer is the graphical arrow.

The same happens if you set resolution to 640x480. Looks like something goes wrong when we switch to kcon and back and VC buttons are not drawn.

Fix in changeset:mainline,1039. Well, I know the support for mouse pointer when use_gcons is false is a little hackish, but I'll leave it for now. Console will undergo a more drastic rewrite anyway sooner or later, most probably when we implement a graphics server.
