The only other thing I can think of is when modesetting kicks in and is 
configuring your graphics adapter? You could try adding the 'nomodeset' 
kernel parameter to your boot, but keep in mind that you will lose 
kernel modesetting, which could potentially cause issues with your 
system. I'm not sure what else would cause the screen to 'blank' like 
you are describing at that point in the boot.
