From Jiri Benc:

we found several bugs in framebuffer console code in recent kernels.

1. The escape sequence '\033[?25l' does not work (should disable cursor).

2. When scrolling console using Shift-PgUp with cursor in the upper half
   part of the screen, cursor position is not updated.

3. If cursor is placed at some character and console is scrolled using
   Shift-PgUp, that character remains on the screen.
