Looks helpful. :) Is there a particular reason you chose not to use the GRUB 
wiki? It doesn't look like this information is OpenSolaris-specific...

That reminds me, how are you booting OpenSolaris using GRUB2 on PPC? With the 
"linux" loader?

I'm actually not sure what you mean by "hardware address translation and the 
memory management layer"... could you elaborate?

From the page:

This is a bug in Pegasos firmware. Genesi was notified a while back but I 
haven't heard anything about a fix. In the meantime, you might be able to run 
"resume" instead of "go" to get back.

If that does work, you could implement a patch that detects you're running on 
CodeGen firmware (the original author) and sets a quirk/feature bit, then 
output a different message in the suspend command. I believe we already 
detect CodeGen firmware to work around a bug I found on the briQ, so you 
would have an example to work from...
