Bug#737750: debian-installer: Netboot initrd does not download ata-modules or sata-modules udebs

[Greg Bell <Greg.Bell@Artemech.com>]

I would like to mention that I've just hit this bug.

I've got a handful of dell laptops here that will install perfectly via 
DVD, but the netboot image fails to load the drivers for the sata 
controller.

I've confirmed that the network is functional, and watched a tcpdump of 
the installer downloading the installer components from three different 
mirrors.

The netboot images are completely missing a handful of drivers according 
to this link:

And it appears that the drivers are not being downloaded from the mirror 
for some reason.
