It's my pleasure to introduct myself to you. My name is Bruce and I'm in charge of authoring SQL Hotfix KBs globally. For our process a cumulative update package for sql server 2005 will be released bimonthly. Our technical guys will triage the hotfixs which will be put into the package. Currently cumulative update 5 for sql server 2005 sp2 was released on Dec 18, 2007 (http://support.microsoft.com/KB/943656). The newer rollup package will contain all fixes that were included in all prior rollup packages. Also, the rollup package is smoking tested.
