Bug#503884: live-helper: the rescue list contains packages that are not on the repository

[Mihai <mihai.militaru@gmx.com>]

Package: live-helper
Version: 1.0.1-1
Severity: normal

My custom list to create an iso image contains the rescue list. This its inclusion depends on two packages that 
are not to be found on the repository:
sl-lmodem-daemon
bcm43xx-fwcutter

It fails with an error when trying to build. I'm building the image for the i386 target and have the "non-free" 
category enabled.
