seeing as RHEL 6 is NOT FREE
have you asked the people over at Red Hat .
You DID buy a license for rhel6 ? right ? Then use your paid for support .
IF you do NOT intend to pay for rhel that do not use it !
Instead instal CentOS 5.5 ( centOS 6 ? should? be out sometime in the next ~3 months)
it is the FREE community supported version of RHEL
