This is interesting: On many BIOSes, grub 0.x is unable to find the CD 
drive and thus many people want us to use isolinux.

 From what you write here, it seems that you can access the CD drive 
through another than the BIOS boot device method. It doesn't matter that 
access is slow, it only matters that we are able to load the kernel and 
initramfs on a greater number of machines. IMO, this is worth looking into.
