I’ve seen instructions for creating an installation
disk with service packs integrated.

What I want to do is a little more complicated, but perhaps
possible by a similar method
I have an installation disk for WIN NT workstation. Plus I have an upgrade disk which upgrades NT to WinXP pro. The XP pro disk only works if there is already a valid licenced version of windows installed. To install XP I have to
- 
install NT 
- 
activate NT 
- 
install NT service packs 
- 
install XP (requires the service packs) 
- 
install hardware drivers 
- 
install XP service packs
