 a) stripping modules (previous patch was wrong, see below)

 Using strip on .ko does not work at all without --strip-unneeded.

 strip -R  .comment -R .note -g --strip-unneeded


 b) bootable iso

 a line like this is required for initrd and it does not hurt in initramfs case

 root=/dev/ram0 initrd=0x00800000,16M
