dynamic values in docked cells

Hello,

the values of symbols in DynamicModule in Mathematica 6 is maintained
across different Mathematica sessions, for example

sliderRow = DynamicModule[{x=0.5}, Row@{Slider@Dynamic@x, Dynamic@x}]

One may change the slider position, close and reopen Mathematica and
find the slider position and value unchanged according to its last
value.

Is it possible to reproduce this feature in docked cells? The
following 2 lines generate a docked cell:

cell = Cell[BoxData   @   ToBoxes   @   sliderRow, "DockedCell"]
SetOptions[EvaluationNotebook[], DockedCells -> {cell}]

However, after closing and reopening Mathematica the slider position
and value is reset to its initial value.

Thanks in advance,
Hannes Kessler
