The drivers are on that disk, I just installed Windows 7 successfully yesterday with a lot of hassle, it's not an easy task getting everything to work in 7, especially the wireless network card, but I just wrote a post that has the links for the realtek audio device and Broadcom wireless drivers in it.
If I remember correctly, once you put in the Mac OSX (DISK 1) cd, when in Windows, the setup automatically runs, but in case it doesn't, just follow your Bootcamp installation instructions. There is also an updated Bootcamp file, 2.1, it's like 280 megs though, so I just downloaded it in MAC, put it on a thumb drive and transferred it over. If you have a problem with any drivers, try that first.
let me know if you need any help.
