A quick test with my -next branch SMP (I haven't tried your kernel &
config yet) and it seems to work fine (well, it doesn't properly mount
root afterward but that's a different issue).

Have you tried the BootX app instead of extension ? That might make the
display work better ?

The kernel should be setting up a raw text display for early output very
very early on, before the main framebuffer driver shows up, I'm
surprised that doesn't even happen.

I'll try the ubuntu kernel & config next, tho I'm a bit unwell today so
I suspect I'll just go home & do that tomorrow.

Cheers,
Ben.
