I mean, the kernel has support for all of those things; they just
weren't included in the binary or in the initrd as modules provided. The
build seems to have been custom-rolled by Robert Milan.

In fact, it seems so custom-rolled that 'apt-get source
linux-image-2.6.31.6-libre1' is an impossible command on my system.

Yikes. Is that even GPL-compliant?

I'll post them here as soon as I have them, and/or document them on the
wiki depending on how much energy for this I have.
