From: Martin Peres <martin.peres at labri.fr> Some vbioses have extra useless entries after "the end" of the table. This is problematic since all of the vbios I found with this issue redefine the pwm freq divider to insane levels (52750 Hz instead of 2500), thus breaking fan management. The first solution to solve this mess would be to change the length of the table. The solution
