Cumulative Hotfix Package - Build 2153

I'm getting ready to install the Cumulative Hotfix Package - Build 2153 on a 2-node, Active/Passive cluster (MSSQL 2005 EE on Windows 2003). I've read through the docs a number of times but don't see any reference to clustering. Should I apply the hotfixes to each node or are the fixes cluster-aware?

Thanks.
I also have a 2-node Active/Passive cluster (MSSQL 2005 64-bit on Windows 2003). I would like to apply the cumulative hotfix, but I too have not found any documentation specific to a clustered installation. Did you install the hotfix on your cluster? If yes, did you have any issues?
