I still don't see any lines about the headphone device in the log.  
Was the headphone plugged in during boot, or did you plug it in later?

Here's what your "registers" file says:

This is very bad.  It indicates that the CPU was unable to communicate
with the EHCI controller at all!  All the memory-mapped I/O reads
returned 0xffffffff.  No wonder the keyboard and mouse stopped working.

I have no idea what could have caused this to happen.  Even if the 
controller had suffered a fatal error, you wouldn't see this.  It looks 
like the bus's connection to the controller was turned off.

I'm CC-ing the PS3 maintainer and mailing list.  Maybe people there can 
help.

Those are normal.  They occur because your system loads ohci-hcd before 
ehci-hcd.  It should load ehci-hcd first.
