Will my dividends be subject to state income tax?

I worked in a state with state income tax (Arkansas) for the first 6 months of 2008, then decided to go to graduate school and moved to a no state income tax state (Texas) for the rest of the year...and quickly became a legal resident and voted as a Texan in the general election! My question is this: I will receive approximately $20,000 in dividend income for 2008 and am curious if those will be subject to Arkansas state income tax; I guess either all will, some pro rated portion will, or none will!
