For using linux it's certainly possible using a simple initrd-filesystem with
smarcard support in it.

If you want to boot windows on this machine, it should be possible too: look
at the kexec-site
        http://www.xmission.com/~ebiederm/files/kexec/
and some links at
        http://kt.zork.net/kernel-traffic/topics/Kexec.html

In short: kexec allows linux to return to real-mode, reset the hardware, and
boot other OS.
So there would be a linux-partition of, say, at most 8MB, with an initrd
image, a minimal kernel with kexec, and the rest of the harddisk could be
used at will.

Of course - that doesn't help with encrypting the filesystems of the other OS.

Phil
