Change Regional Setting though registry/kitchen???

[Mystery]

When you go to Start>Settings>System>Regional Settings my option is set to English (Canada), my question is how can I set this to English (United States) though the kitchen? I have already tried doing it as a registry edit in "my Registries OEM", as a .provxml, and as a registry cab install during customization.

This registry is pull off from here:

[HKEY_LOCAL_MACHINE\Security\ColdInit]
"Locale"=dword:00000409

That is exactly how I want the registry to look, with 00000409 as the dword but it doesn't change when I flash my ROM. I'm currently using the latest Calkulins' kitchen with 21231. Do you guys have another way I can change this though the kitchen??? Thanks!
