2.4.21-ben3 : - Disabled DMA in the macserial driver, this is causing some
                silent memory corruption. I'm rewriting this driver for 2.5
		anyway.
              - Update HFS+ snapshot to what is in 2.4.22-rc3
              - Fix a problem enabling DMA on some setups where the DVD drive

              - Update ieee1394 to the version in 2.4.22-rc3
	      - Fix mediabay, got broken with 2.4.21 new IDE layer
              - Make sleep & cpufreq more robust regarding possible
	        ADB interrupts getting it at wrong moments, fix the
		spurrious empty ADB messages we got after each real
		one.
              - Improve .coff images, they should work with up to
	        about 2.9Mb .coff files and large uncompressed kernels 
	      - Update radeonfb to 2.4.22 version
	      - Include Samuel Rydth better timebase syncing code
