Quite possible. These days AUR generates an RSS feed which
can be used in the newsfeed desklet which makes aurfeed
mostly redundant. Gentoo has the same features, just pick
your arch at
this
page and pass the URL of the feed you want (simple, so
you don't get HTML crap with it) to newsfeed and it should do
the same thing.
Let me know if you run into any troubles :)
