Ohh.... Hmm...

If you have an existing linux installation then do the following:

1. Copy the iso image to the hd somewhere.

2. Mount the iso image using the loop device

mount -oloop whereever-it-is.iso /mnt

3. Copy the tree somewhere else

cp -a /mnt cdroot

4. Now you can run the CD environment using chroot

chroot cdroot

5. Use the networking of the host environment to install the
kernel-headers

apt-get update
apt-get install kernel-headers....

6. Compile and install your driver

7. exit chroot environment

CRTL-D

8. Rebuild the iso

mkisofs -R -l -o mytbox.iso -b isolinux/isolinux.bin -c isolinux/boot.cat
      -no-emul-boot -boot-load-size 4 -boot-info-table  cdroot

9. Burn ISO image

10. Boot from CD on the other PC.
