When I had enabled the proposed 3.0.0-15 kernels, there were no
linux-header packages for them. Today when I saw this might be a
problem, I re-enabled the "proposed" repositories and checked again.
Still no linux-header packages.

But after I sent this email, I went and checked a second time. Lo and
behold, they were now available, so I installed them. I then was
successfully able to build Scramdisk from source as per Jonathan's
instructions. There must have been a time delay between my re-enabling
the proposed- repositories and the updates showing themselves as
available.

Thanks, Jonathan.
