I'm trying to get it installed on my sdcard but cannot get the kernel installed. I setup the card, downloaded and extracted the archive (I've tried both the n12_umay and the n14_dev from the dropbox), which seems to work fine, but when I try to install the kernel (I tried both on the dropbox), I get:
dpkg: error processing <kernel> ...
unable to make backup link of ./and/system/lib/modules/<module dir>xt_tcpmss.ko before installing new version: Operation not permitted.
(it's that file on rc7 kernel and aipt_ECN.ko on the rc4 kernel)

Suggestions or ideas?
Thanks.
