Default Hyperdrive RLS 12 on i970 and USCellular

I always up installing the latest version of Hyperdrive and invariably there are ways some slight issues. I seem to remember when I stepped up to 10.1, I installed the ROM, then the upgrade and if I remember correctly, I had to add a new kernel. SO what is the trick for RLS 12 final? I have did this and when I reboot is hangs. Any pointers would be appreciated!
