Not really said much on this subject, about the paltry political donations (compared to the costs of, for example, the Iraq war,) or indeed about how it has affected me generally.
For now I'll just highlight a blog, which I think is well worth a look at if you want to help, but don't know how to (aside from purely giving a donation).
Do check out The South-East Asia Earthquake and Tsunami Blog - which contains news and information about resources, aid, donations and volunteer efforts.
It's particularly useful for people who want to volunteer and want to know how to go about it - have a look and see what happens.
