Yeah, but this problems seems purely due to the pata-modules missing in
the initramfs.

Could you explain a little more? With the "common" directory you mean [5]?

The way I understand it, the configuration files in [6] control what
UDEBs are built for the alpha kernel used for the installer, as they
seem to include the configuration files from the assumed "common" super
directory which list the drivers to include for the respective
devices/protocols/standards/etc..

And the configuration in [7] seems to control what UDEBs are installed
in the initramfs. This would make sense for [7] as it looks like the
alpha configuration file for the installer CDROM and the initramfs for
this CDROM should contain all needed drivers to be able to access the
used disc drive. Hence I think we need to update [7].

The question remains if one needs to specify dependencies explicitly or
if dependencies are resolved during build. I'll try to correlate the
modules in the initramfs with what is configured in [7] and come to a
conclusion.
