Now, may I assume you got the messages in the following order, the
return code was "fa" ("zz" in the fifth line) and the keyboard did NOT
freeze?
sc0: enabling tty intr. (set_keyboard)
sc0: about to send command and data (set_keyboard)
sc0: kbdc is LOCKED!! (scintr)
sc0: kbdc is LOCKED!! (scintr)
sc0: command:xx data:yy ret:zz (set_keybard)
~~
sc0: kbdc is LOCKED!! (scintr)

Please revert to the original syscons.c and apply the following patch.
It is known to work, that is, kbdcontrol can change key repeat rate
and the X server doesn't lock up the keyboard.
This patch doesn't generate debug messages, so it will be more
suitable for daily use than the previous one.
