No, it doesn't actually need a special config.

I can run bog-standard Fedora Core on it, except it needs to be the 
current development tree in order for grub to not lock up (and again, that 
was very arguably a grub _bug_ - the Mac Mini doesn't have a keyboard 
controller, it has USB only, but grub would wait forever for the 
nonexistant kbd cntroller anyway).

So it's not a "legacy PC", but it's certainly "standard Intel chipsets 
with ACPI". So the same image _should_ really work.

Of course, like any other PC, it has its own quirks (aka bugs) in the 
firmware.

I know. On _some_ machines. So far, I don't think I've actually ever hit 
a machine where it "just worked". Every single time there's some module 
that needs to be unloaded for it to boot, or it needs to use fbcon, or it 
needs some other magic.

I'd really like for it to "just work", and having more people who can try 
to debug why it doesn't work for them is probably the best way to get 
there. I know from personal experience that at least _one_ reason why 
people didn't even bother debugging it was that there simply wasn't 
anythign to debug. There was just a dead brick.

It's that "it's just a dead brick" part I want to fix. I want to turn that 
into "it's a dead brick that I can look inside".
