Why the removal of crypto-sources? I have an encrypted root partition, so I need the encrypted loopback in order to boot my machine. BUT I have experienced significant, consistent problems with firewire in the post-2.4.19 kernels. So I need the option to use a 2.4.19, which rules out gentoo-sources or lolo-sources. I will check on using a gentoo-sources-2.4.19 kernel --- but I'd rather have my known-working kernel as an option! (Yes, I have a backup of this ebuild...) Thanks VERY MUCH for the WONDERFUL kernel options available in Gentoo!
Drop crypto-sources, please use xfs, lolo, or gentoo-sources.
lolo has crypto api in it so it should work for you ...
