DSL Embedded :: How to make custom dsl cd/dvd

I have figured out how to remaster my dsl livecd what I cannot figure out is how to get these programs onto the new master..I would like for my sound card driver alsa to load and to get gimp to load at bootup time..I can get these programs to work if I am already in dsl so I know they work ok

I know what files I need and have them download as well
just not how to get them into the new master

Please help thank you
