this kernel is also the first one to support Toshiba, Sony, and IBM's CELL processor
The new Linux kernel also has support for Mac OS X's newest file system: HFSX. This is the latest update to Apple's HFS Plus (Hierarchical File System Plus) file system. HFS Plus and its descendents have been the Mac's default file system since Mac OS 8.1. HFSX appeared on Macs beginning with Mac OS X 10.3, Panther.
