hardware partitioning could help

All IDE hard disks have microcontrollers on them. Why not implement a security based file system through this interface.
(you log into the hard disk, the hard disk stores passwords or security keys on it)
Also, if you pare supervisor mode microkernel down enough, you could have a seperate supervisor mode only microcontroller controlling the normal general purpose processor, which only ever runs user mode processes (even if they are video drivers).
Access to physical MMU pages by the User mode processor is impossible, and there is harvard architecture (allow-execute-bit in MMU page descriptions).

How do you make the software in the supervisor cpu and hard disk bullet proof? Make it simple, and as little of it as possible. Audit it, etc.
Upgrades of this would be unheard of.
