So far i have placed my suptitles above the frame, like this:

Your solution using text
is also my go-to solution. However, you don't need to compute the position based on xlim and ylim. If you set transform=ax.transAxes
the coordinates for positioning the text are taken as being relative to the axes bounding box (0,0 being the lower left corner). Like so:
data = range(1,10);
fig = figure()
for i in range(6):
ax = fig.add_subplot(2,3,i)
ax.text(.5,.9,'centered title',
horizontalalignment='center',
transform=ax.transAxes)
ax.plot(data)
show()
Hope that helps!
