I also had some problems with the extensions in RC2. A lookup for 
extensions always returned no result.

Here are the steps I did to fix the problem:

- "Enable unsupported extensions" in setting of the Extension manager
- Raise the memory limit in php.ini to a value greater than 32 MB
- Remove all temp-files in typo3conf
- Remove all temp-files in typo3temp

After that, the extension manager worked fine.
