Vista Custom Search Provider Publishing using Windows Server 2003 Domain Group Policies

From some searches I've done, it looks like Windows Vista has updated it's group policy templates from ADM to ADMX format, which is no longer editable in Windows Server 2003's group policy editor.

I know how to change the Vista Instant Search's Custom Internet Search Provider (to point to our local SharePoint 2007 server for intranet searches) locally on a particular Vista workstation, but I can't figure out how to publish a domain group policy that will update all Vista workstations to use this custom intranet search provider using group policies the way I can for XP's Windows Desktop Search v3.01.

If anyone could point me in the right direction, it would be much appreciated.
