Bug#500283: [installation-guide] Please clarify which Optional kernel modules should be used to create a flexible USB Memory Stick (4.4.2.1)

[Filipus Klutiero <chealer@gmail.com>]

Package: installation-guide
Severity: wishlist

4.4.2.1. USB stick partitioning on Intel x86
contains:

copy the following files from the Debian archives to the stick:
[...]
Optional kernel modules

Although the "from the Debian archives" is quite vague, the file name helps to 
find the first files. Finding "Optional kernel modules" seems to be harder. 
Unless I'm missing something obvious, this pretty much makes the section 
useless.
