CS2 doesn't recognize DNG 5.4 converted files.

Question

Ran the new DNG converter files on Panasonic LX2 RW2 files.  The conversion went well. When I tried to open up the files in either Bridge or CS2 I get: Could Not Complete Your Request Because Photoshop Does Not Recognize This Type of File.
The older DNG converter worked fine.
Any suggestions?

Gabor, Simon,
To clarify my earlier (admittedly brief and not very helpful) post, we must be careful to distinguish between the raw image data itself and the (possibly required) processing of that image data. The raw mosaic image data itself from a .RW2 is certainly compatible with earlier DNG versions (e.g., 1.1, 1.2). However, the reason that earlier versions of Camera Raw create linear DNGs, instead of mosaic DNGs, is given in Tom Hogarty's CR 5.2 release notes:
http://blogs.adobe.com/lightroomjournal/2008/11/camera_raw_52_and_dng_converte.html
To quote the relevant section directly:
This exception is a temporary solution to ensure that Panasonic and
Leica's intended image rendering from their proprietary raw file format
is applied to an image when converted DNG files are viewed in third
party software titles. The same image rendering process is applied
automatically in Camera Raw 5.2 and in Lightroon 2.2 when viewing the
original proprietary raw file format.
In
a future release Adobe plans to update the DNG specification to include
an option to embed metadata-based representations of the lens
compensations in the DNG file, allowing a mosaic DNG conversion.
We can debate what level of processing is required to obtain an acceptable image.
However, the original claim -- stating that "The raw data of several Panasonic cameras did not fit to the imagination of the DNG designers" and then concluding that this is the reason that "the raw data had to be converted in 'linear' format" -- is incorrect.
