custom folder instead of /boot

[mpodkost <mpodkost@gery.pl>]

Hi,
is there a way to force linux-image-* package to be installed in a 
custom folder (in my case /boot/debian/) instead of /boot/?
As i can see "my realimageloc=/boot" might be problem or location in .deb.

The goal is to make system automatically install any future
config-*
vmlinuz-*
System.map-*
in custom folder (ie. /boot/debian/)

Will be appreciate for any help or clue.
