I don't doubt it. I pretty much knew when I bought the K7S5A that upgrading would be limitted. I think i'd be better off getting a new board and a Barton based Semp. My 1800+ (thunderbird) runs hot. When I built my system, I had to put in two case fans just to get it to post. The Athlon 2000+ (Sempr0n 2400+) must be one hot running chip (or I was just unlucky with mine). Also, at stores I usually buy from, the Semps are cheaper than the Athlon equivalents. I believe that the K7S5A only has 256 FSB support. I guess if I had to do a budget upgrade, I'd switch to a Nforce 2 board and go with a Sempr0n. More likely though, I'll buy a new system in a year or so and use this one as a HTPC hub.
