I couldn't get this 2.6.22 kernel to boot so I took the XFedora kernel lalee created from here, back ported the FATX and partition table changes from 2.6.22 that I earlier patched into this tree and this was able to boot. I will post the kernel tarball.
I did very preliminary tests ( a mount and cp -r ) on the 32K clustered FATX partition F and files were copied without errors. A reboot and UnleashX was able to launch one of the XBE (XBMC).
I've used the kernel as the basis for a chimp26 remake.
