UEFI Secure Boot and Ubuntu - implementation

[grarpamp]

What specifically is Canonical/Ubuntu doing to contact the OEM
(Quanta/Compal/etc) and Retail motherboard manufacturers
(ASUS/BioStar/MSI/GigaByte/Intel/etc) in order to:

- Query and ascertain their plans for UEFI Secure Boot implementation?
- Ensure that motherboards purchased by Ubuntu users for their
systems will allow the platform owner (said users) to install (or
replace) the Platform Key (PK) in SetupMode on said motherboards
per the process outlined in the UEFI Specification Chapter 27 [1]?

What have the results of any such conversations been to date?

Being able to manage the Platform Key (PK) independant from third
parties such as Microsoft (indeed any OS provider) is obviously the
most desired case.
