you think that might be the problem? I wouldn't be surprised. I'll try from a recent snapshot and see what happens.
edit: tried from the download link you gave, but that snapshot appears to be from the wrong kernel. I am able to download the files and they don't appear to be corrupt, BUT. They still give an error:
root@Arduino:~# opkg install /mnt/sda1/Util/kmod-input-core_3.10.36-1_ar71xx.ipk
Installing kmod-input-core (3.10.36-1) to root...
Collected errors:

* opkg_install_cmd: Cannot install package kmod-input-core.

@Federico, if you could turn on directory browsing, it might fix the problem. It is possible that is why the files are downloading corrupt.
I'll try downloading from here:

edit 2: still getting a kernel error
