current list of distos which support Alphas?

I'd like to upgrade a DS10L which currently runs an old version of  
RH.  I see that CentOS 4.3 and Debian 3.1 both support Alphas.   
Unfortunately it appears there's no longer an Alpha version of Suse.   
Do I have this all correct?  Are there other current distributions I  
should look at?  I'll probably go with CentOS because I have no  
experience with Debian.
