[CentOS] Using yum 2.4.x under centos3

Hi all,

  Somebody have test it yum 2.4.x 
(http://linux.duke.edu/projects/yum/download/2.4/yum-2.4.3-1.src.rpm) under 
centos3??

  I have installed an mrepo RHEL5 server to serve updates for rhel3, rhel4, 
rhel5, centos3, centos4 and centos5 (when becomes GA) and RHEL5 doesn't provides 
yum-arch ...

Thanks.
