"Collie" is a codename for the SL-5500. Do you mean you want an alternate ROM installed in an optimized fashion?
EDIT: If this is what you mean, you may want to specify what ROM (pdaXrom, OZ, Cacko, etc.) you want installed.
Just as a note, I have no experience with non-SL-Cxx(x) models, so you probably don't want me trying to install a new ROM for you.
