I did a bit of dumpster diving, commit cea6a4ba8acfba6f59cc9ed71e0d05cb770b9d9c
("[PATCH] panic_on_oops: remove ssleep()") removed the 5 second delay
from ARM, i386, ia64, powerpc, x86_64 and xtensa on 2006-03-07.

The idea once upon a time probably was to keep the panic message on the
console long enough so somebody has _maybe_ a chance to read it.  Which
is a pretty weak solution.
