This depends on what you call "managed" code.
Obviously you need a HAL (because you can't express some direct hardware
access in C#) written in another language.
Then you need a kenel, which (at least partially) needs to be compiled to
processor specific instructions (which can also be done from IL). You still
can have code verification and garbage collection at that level even if you
compile down to native.
Singularity has several other aspects that seem interesting. Especially
using exclusively verifyable code and with that they don't need kernel/user
mode anymore and they can operate without any hardware context switches
which potentially could make a very-high perfomance kernel.
Then you have device drivers which singularity reportedly implements in
verifyable managed code.
And last you have some shell oder execution mechanism, which can obviously
be done entirely verifyable managed.
