I think it goes like this. I'm assuming pxe.
cat <initrd> | gunzip | cpio <some options>
Inspect the tree you've created
Pop the driver module in place (there may be a further cpio or similar 
archive you need to open). Repack if necessary
read linuxrc to see where it goes. Change whatever seems good
find <some options> | cpio <some options> | gzip ><initrd>
test boot.
repeat as necessary.

If you're booting from CD, you can do the above, but you need to unroll 
the ISO first:
mount -o loop ... /mnt/iso
find /mnt/iso -name TRANS.TBL -exec rm -vf {} \;

Find the imbedded boot floppy and mount that.

Do as above. You may need to remove the initrd from the floppy before 
putting it back.
mkisofs <I think the magic incantation can be found in anaconda>
cdrecord <burn to cd-rw or dvd-rw, you don't want to go through a 
spindle of media for this>

Note, I have assumed your driver's built to match the install kernel. 
This is necessary.


Wonder what to do for the next ten days.
