I am not sure why RIM downplayed it in their announcement but the new version of their SDK (v0.9.3) now clearly supports Linux development. So far Linux development support is only available for the Tablet OS AIR SDK but hopefully the WebWorks SDK will get Linux support. The Linux SDK supports the following Linux distributions: openSUSE 11.2, Ubuntu 9.1, or Fedora 12.
You can catch the instructions and download info at:
