I'm familar with 48 sun v20z (newisys) machines around here, only one
died so far with a hard memory error (I.e. won't boot).

We also have 40 ish Tyan systems without any failures, all were burned
in by the vendor.

Speaking of which, has anyone done anything useful with the v20z LCD
display, ours just say something like IP address of the management
interface and OS booted or similar.

I was hoping for hostname, maybe system load, even a way to pull a node
out of the queue (there are several buttons under the LCD).
