Note that B1 security doesn't even begin to address many significant

If someone gains root (or even runs a non-framebuffer X server), that
violates any sort of "Trusted Path" assumption that would be inherent
in SAK.

However, there already is an SAK implemented on every pc in existence:
the power switch.

[This does make some assumptions about the sort of circumstance where
you'd have multiple users and need a secure attention key. But those
assumption seem right for most cases I can imagine.]
