Here is a mapping for Sun type 5c/6 keyboards :
http://temlib.org/pub/sun/keyboard.pdf

The International keyboard arrangement have one more key than the US, but codes 
are otherwise identical.
These keyboards still identifies as "Type 4".

For US/QWERTY, the layout should be set to 0x21 : (hw/char/escc.c)
     case 7: // Query layout
     case 0xf:
         clear_queue(s);
         put_queue(s, 0xfe);
-         put_queue(s, 0); // XXX, layout?
+         put_queue(s, 0x21); // USA layout
         break;
     default:

Here is a mapping with corrected codes for arrows/pgup/pgdown... :

The sound control and power keys are still lacking. but QEMU does not emulate 
the sound anyway.

I have tried a 119 keys Sun USB keyboard but the additional keys do not seem to
be detected by QEMU. Needs more work...
