Well I'm not sure what *should* be happening, but it seems that I can 
manually boot the ramdisk by hand after the initial expection, e.g:

boot cdrom

And then when the exception is thrown, manually boot the ramdisk with:

boot /ramdisk-root

This gets things a bit further but it looks like we need a module or 2 
included for SPARC64 which aren't in there already.

Tarl: is this nested boot process something that auto-boot should handle 
automatically based on various bootarchive properties set by the initial 
Fcode loader?
