rescue reiserfs on raid

[Ben Hildred]

I need to copy some files off of an old system that users reiserfs 3.6 on
an old hardware raid that most rescue cds wont work with. Fortunately when
I pulled out my favorite tool Debian's installer recognized the raid and
correctly identified all the partitions, but the reiserfs would not mount
and I did not see the udebs (
https://packages.debian.org/jessie/reiserfsprogs) listed as available. Does
anyone have any guidance on how to proceed.
