huh?
OBP on E25K's was always present for the adding and removal of CPU,
memory, and I/O devices...
Not sure I see how that makes a case for removing it. ;)

That's mostly because the OBP relies on a static configuration
initialized when the system (or a domain) is started, and it does
not support things like dynamic reconfiguration (e.g. add/removing
cpu while the system is running). If the OBP was kept then it
could become out of sync compared with the actual configuration.

Alex,
On sun4v platforms, when Solaris boots, the OBP is removed from
the memory and you can not used it anymore when Solaris is running.
This is done in order to properly support virtualization (with
Logical Domains).
BTW, why would OBP need to be removed for virtualization purposes?
