	That's because it's still loading the 2.2.6 kernel
	at bootup.  The bootstrap loader (yaboot, in this
	 case) hasn't committed any changes to the MBR or
	wherever it's stored.  I don't have much experience 
	w/ PPC Linux (and even less w/ MkLinux), but Linux 
	is Linux.  <--- that should start a flamewar!

	OK, remove the symlink, because that won't work.
	Look at your /etc/yaboot.conf file and check the
	location of the boot image.  It'll be on the line
	that begins `image=`  Make a backup of that file
	(probably /vmlinux) by copying it to a new location.
	Then copy your new kernel file to that filename,
	paying no attention to the fact that `make` gave 
	it a different name.  Then run `ybin` and `reboot`.
	That should be all it needs.  Pretty much the same
	steps for an i386 kernel rebuild w/ LILO.
