Cannot confirm nor deny that you can or can't do this in an existant or
non-existant beta or other version of current or future software.
Alternative would be something like Blankworks.
Sorry, it can't be done in current or older versions of SolidWorks. A flange
on the edge of a curved face requires that the material be drawn, not just
bent, and SW can't handle that. SW2007 is supposed to let you put a flange
on a curved edge of a flat face, which also requires drawing, but I don't
remember any claims to make something like your part. I haven't tried the
Beta code, and if I had, like Matt, I couldn't tell you about it because of
the non-disclosure agreement.

Someday, when I am king of SW sheet metal development, stuff like this
will be 2 mouse clicks from the design library, and a more complex
transition will be just a little harder. SW does keep adding sheet
metal features and generally is getting better with each release, so
don't give up on it yet.
What I'd do for this is make the model fully formed for the assembly
and drawing with extruded lofts or surfaces, and make a separate flat
part for the development drawing view, or if it's just a rectangle, use
a drawing note for the flat size. If you do a lot of these that are
similar you could model one and use a general table to show the
different sizes in your drawing.
To do it cosmetically...You could use the Flex feature to bend it. Then
suppress the Flex feature to get the flattened the pattern to work.
Depending on how much you care a about the correct values on the flat
pattern tho, you'd have to fudge those values on your own because the
k-factor (or whatever method) here would be useless.
Calling this feature a channel beam, the following:
As long as you now know that SWX Sheet Metal is unable to accomplish
what you want, right now, why not simply extrude a cylinder, the width
of the channel beam, and of the radius that you require. Using the
wrap feature, depress the channel itself, in from the outermost edges,
leaving the desired thicknesses of the outer walls, and the depth of
the channel would determine the length of the walls, then trim
everything else off, leaving a sheet metal appearing part. For the flat
version, an extrusion to the length of the channel beam of the
cross-section of it would be what you need. If you wanted to get real
fancy, use a slight fillet at the bottom of the channel depression and
a slight chamfer of the outside edge of the cut, to simulate the
natural radius that you would get drawing sheet metal up 90 degrees.
