100% is surely not our goal (e.g. we are not interested in providing a 
framework to build an EFI Application), but if anything is relavant to 
booting, it should be supported.

Do you know what these drivers are? Also, if I want to confirm what are 
required on my machine (the first generation of Mac Mini), what should I 
perform? I expect that they must be identical among different models more or 
less, but I think it would be better to verify it on some models.
