matroxfb: restore the registers M_ACCESS and M_PITCH When X11 is running and the user switches back to console, the card modifies the content of registers M_MACCESS and M_PITCH in periodic intervals. This patch fixes it by restoring the content of these registers before issuing any accelerator command.
