In the Kconfig option in the kernel..

+config BOOT_DELAY
+   bool "Delay each boot message by N milliseconds"
+   depends on DEBUG_KERNEL
+   help
+     This build option allows you to read kernel boot messages
+     by inserting a short delay after each one.  The delay is
+     specified in milliseconds on the kernel command line,
+     using "boot_delay=N".
+
+     It is likely that you would also need to use "lpj=M" to preset
+     the "loops per jiffie" value.
+     See a previous boot log for the "lpj" value to use for your
+     system, and then set "lpj=M" before setting "boot_delay=N".
+     NOTE:  Using this option may adversely affect SMP systems.
+     I.e., processors other than the first one may not boot up.
+     BOOT_DELAY also may cause DETECT_SOFTLOCKUP to detect
+     what it believes to be lockup conditions.
