Which RAW processors apply embedded Micro Four Thirds lens corrections?

Many Micro Four Thirds cameras and lenses store distortion and chromatic aberration correction data in the RAW metadata. I’m trying to find out which RAW processors actually use that embedded correction information.
Specifically, do Adobe Lightroom / Camera Raw read the correction data from the RAW files, or do they rely on their own lens-profile database? I’m also interested in Linux-compatible options if possible.
If a RAW processor doesn’t support the embedded corrections directly, is there a practical way to generate lens correction profiles separately for use in other software?

In the thread from Bibble Labs that you linked to, there is a post that refers to a tutorial on using Hugin to create lens correction profiles. I used that technique over a year ago with Bibble and found that it worked. Hugin runs under Linux.

Generated from our catalog & community — verify before relying on it.
Based on the community answers, Adobe Lightroom and Camera Raw do apply the embedded Micro Four Thirds lens corrections automatically. For Olympus and Panasonic Micro Four Thirds combinations, Adobe appears to use the metadata written by the camera/lens system, and users report that the correction cannot be disabled in Lightroom/ACR.
For Linux, a practical option mentioned is Hugin. It can be used to create lens correction profiles, and at least one user reports successfully using that workflow with Bibble. So if your current RAW processor ignores the embedded metadata, generating a correction profile with Hugin may be a workable alternative.
In short:
- Lightroom / Adobe Camera Raw: yes, embedded MFT corrections are applied automatically.
- Bibble: does not appear to use the embedded correction data directly.
- Linux workaround: Hugin can help create correction profiles for unsupported software.
