Subject: Trying to get my shiny new G5 (quad 2.5GHz) to boot under Linux

I just bought a brand new absolute-bleeding-edge Quad 2.5GHz G5 (it's  
actually dual-proc dual-core, but that's marketing for you) and I'm  
trying to find a kernel that will boot the system.  Well actually I'm  
_trying_ to install Debian but I have yet to even get to mounting the  
initramfs.  Here's a list of the kernels I've tried:

   Debian-Installer beta2 (I think this is 2.6.15?)
   Debian 2.6.16-1-powerpc64
   Debian 2.6.17-1-powerpc64
   Custom 2.6.18-rc2+git (64821324ca49f24be1a66f2f432108f96a24e596)

The first two Debian kernels didn't get past "Setup Arch" in the  
OpenFirmware text console; they just hung with black text on a white  
screen and spun the fans up to full blast after a few seconds.  I  
_think_ they were missing a PowerMac dual-core fix of some kind that  
went into 2.6.17, although my googling wasn't terribly informative.   
The third debian kernel got into driver init code and failed when the  
i8250 serial driver claimed some resource and broke the zilog serial  
driver.  I couldn't figure out if a fix for this ever made it into  
the latest kernel, so I built a custom kernel for my G5 from my older  
G4 (ARCH=powerpc).  This kernel dies in the SMU code with the  
following panic (WARNING: Typed by hand from the console, so there  
may be small typos).  My .config is attached.

If you have gotten Linux to boot on the Quad G5; I'd really  
appreciate it if you could send me a working .config (or even better,  
a working vmlinux image).  Thanks for all your help!

Cheers,
Kyle Moffett
