It sounds like you haven't included the modules for airport and your 
network card in your kernel.  Make sure that they are at least marked 
<M>, but I prefer to build them into my kernel (marked by <*>).

You haven't compiled in a framebuffer device.  On that machine you need 
to have RadeonFB compiled into your kernel.

You'll need to have support for HFS+ compiled into your kernel.  Make 
sure that it is compiled in.  For HFS+ filesystems, the type is hfsplus, 
not hfs.

Yeah, I'll need some more information to help you with this.

It should be working, as you said initrc is spawning the terminals.  On 
my powerbook, I press Alt + F# to switch the terminals, but if you're 
not running pbbuttonsd, you'll need to press fn + Alt + F#.

Good luck!
