but the issue here is accountability and valuation. can you accurately keep track of the cpu donations in an accountable way? if you write a check, that leaves a paper trail. not sure how to do a similar thing for cpu cycles. also, how to value what you donated..? can you accurately evaluate how much those cpu cycles are worth?
as i mentioned before, i don't think you can say, during business hours, i earn $$$ amount per XXX cpu cycles so if donate so many cycles, it's worth so many dollars. because by definition, the cpu cycles you are donating are "unused" ones. the reason they were donated to begin with is because you weren't using them...
again, i'd check with stanford/folding team.
by the way, possibly related to tax deduction, you have to agree that anything that come of your participation in folding/seti/etc. is not personally attributable to you. you cannot claim patent or credit for having folded a particular protein that leads to a breakthrough in medical progress or having analyzed a particular signal confirming the existence of an extraterrestrial intelligence... so i'm not sure the same applies to "donations" of cpu cycles. i'm not sure if you can claim it as such...
