As of Spring 2012, Exped makes a FlatValve Adapter that allows you to use the Schnozzel Pumpbag (or any Exped pump for that matter) with mats that contain the integrated pump:

Alternatively, there is the DownMat UL 7 LW which comes with the Schnozzel Pumpbag standard. This mat contains a 20 denier shell fabric (as opposed to a 70 denier shell fabric in the standard DownMat 7 with integrated pump), and as with all ultra light gear, needs to be treated with a little extra care:

Beyond that, they do not make a DownMat 7 (standard weight) with a Schnozzel Pumpbag rather that the integrated pump.
For Spring 2013, they will have the new DownMat XP 9 LW. This will be a standard weight (70 denier) mat (9 cm thick) that comes with the Schnozzel Pumpbag standard. The idea behind this is that in the extremely cold temps (approximately sub -35º F), the integrated pumps begin to lose efficiency. This mat will be offered in the 9 cm thickness only (for those extreme temps), and comes with the Schnozzel Pumpbag for the most reliable inflation in those temps.
