Thanks for the suggestion. It turns out the radeon driver was not 
loading at all. I got that worked out by getting rid of nomodeset boot 
parameter, but still had issues with bad graphical distortion. I ended 
up chatting with a helpful fellow on freenode #radeon. Equally stumped 
after looking at my dmesg and xorg log then suggested adding 
radeon.dpm=1 boot parameter(turns on power management). Now its working.
