OK,

I'd like to wait until some of the current patches get in, so as to 
avoid a case of patch-versionitis.

I mis-spoke earlier about who the intendend consumers of the printk'ed 
messages are; rtasd already implements its own kernl-to-user interface
via the /proc interface.  Yes, everything in /proc/ppc64 is prolly 
deprecated, but lets put this off till later.
