booting an E10K?

[tgpt]

So here's an off-the-wall one for you:

We have an E10K (24 33mhz CPUs, 10gb RAM) that's going to be traded back in to Sun. It's been retired from active service and we want to play with Linux on it. I'm figuring maybe one of you has gotten to play with one before, so I figured I'd ask here.

I think the trouble I'm having relates to the E10K's lack of a real console. It has no serial ports, no keyboard port, and no monitor. You get to the PROM over the network via an Ultra 5 using the SSP net console tool. It works OK when accessing the PROM and I can boot from CD and use SILO, but once I try to boot Linux the world just goes away. I see:

boot: gentoo serial
Loading initial ramdisk...
Remapping the kernel... done.
Booting Linux...

and that's it. I can't tell if the machine is running (cylon lights are still moving, but I'm not sure that means anything).

(I'm using the latest gentoo sparc64-rc4-2 iso)

Tips/pointers anyone?
