Yellow Dog Enthusiasts, IBM has posted "Yellow Dog Linux on Power Mac G5: A Linux on Power developer's workstation", a preview of 64-bit Y-HPC on an Apple G5. While this preview is of a hand-built YDL v3.0.1 + 64-bit component hybrid, it does offer a glimpse of what is to come. http://www-106.ibm.com/developerworks/linux/library/l-ydlg5.html?ca=dgr-mw05LinxOnG5 --TSS Team
