Using the ubuntu 2.6.33-020633-generic kernel, setting new_pll=0 makes 
the system unusable.

 From the time it goes into graphics mode just prior to gdm starting, 
the screen blinks to black every few seconds, then returns to normal for 
a second or two, then repeats this sequence.

How can I check if this patch has been applied to a ubuntu kernel image?
