First: It is ALT
attribute and NOT ALT "tag".
And to make it further clear: We are talking about the TITLE
attribute and NOT the TITLE meta tag. Don't confuse this.
See
http://www.w3.org/TR/REC-html40/struct/global.html
for explanations.
Having said that: By using the title attribute you can and should provide additional information about an element (not just a), where it is appropriate. As for links, WAI recommends:

Content developers should use the "title" attribute in accordance with the HTML 4.01 specification. For example, "title" should be used with links to provide information about the target of the link.

So do not use it for keyword stuffing. Use it with your users in mind - title attributes are displayed by many browsers as a tooltip and can provide valuable information about a link. It can even help to bridge the gap between
SEO and USABILITY: You can use a an informative link text containing keywords (if appropriate and making sense ...) and use the title attribute to explain what you get when clicking this link. Note that tooltip display is restricted to 64 characters (afaik).

for further suggestions.
I have no reliable information whether the SEs do analyse title attributes - the opinions are mixed.
My personal opinion is that SEs should not analyse ALT attributes at all, but use the TITLE attributes. That way, ALT attributes would not be used anymore for KW stuffing and could return to their proper function: To improve navigability of the page when images can't be displayed.
