I don't know about any "official" announcements, but Linux PPC isn't listed on the applications page. As an avid OS X PPC user, it's harder and harder to find work for my machine; I imagine the user base is probably even smaller for Linux?

WUprop PowerPC Linux:

Here's the projects which still support OS X PPC, fewer and fewer all the time. I know SIMAP will be disappearing by the end of this year, due to their discontinuing the BOINC side of their project altogether.

Have you looked at your event log lately?

Older hardware will eventually get phased out as updating applications for them becomes too time and resource-consuming compared to their contributions to the project. There are only a handful of projects that are still around which can crunch on PowerPC processors, MilkyWay being one of them. I still have a handful of those machines (a bit of a hobby) and my "workbench" machine, a Dual G5, still completes work though mostly for Moo!, Enigma and SIMAP because MilkyWay tasks are usually too long to complete on time within my usage pattern. Similar processor restrictions exist for some other projects; BURP requires a 64-bit processor, others require specific instruction sets such as SSE3, etc. You might quote statistics about cost versus efficiency, but they are moot when I would be using the machine anyway; in my case I only have one host that is on 24/7, the rest when I'm in the office or actively using them.

I absolutely agree with the "anything helps" philosophy, and it's my understanding that it's one of the reasons BOINC and grid computing in general was developed. I understand that supporting older hosts can become too difficult for the benefit, but I appreciate it when projects take the extra time and effort to do so. You may not see their contribution as significant, but it matters to people like me, and "contribution" can be pretty subjective depending on a project's function and goals.
