Can Matlab 2011b dsolve command solve the 4th order beam deflection equation?

I am looking for some help using dsolve to come up with a solution to the attached equation.

The newer versions of symbolic toolbox can use the diff() command within dsolve. What I'd like to do is something like this but in the syntax used in 2011b:

u1(x)=dsolve(diff(diff(bending_stiffness,2),2)=w)

Could somebody please help me out with the syntax I need?
