F16 upgrade: No space in boot (2 different errors)

[GODhack]

I tried to upgrade to F16 and preupgrade failed with no space on boot so I wiped out old kernels and memtest and preupgrade completed ok then.
Then I rebooted and tired upgrade and upgrade itself now demands one mb more.
That should not happen, but main question is where I can get one more mb now?

If you can boot the old setup try this, it should reduce the initramfs image by at least 4Mb.

su
dracut -f -H -v /boot/initramfs-$(uname -r).img $(uname -r)
