Woah, that's new.  And wrong.  The code in include/asm-i386/param.h that
says:
	# define JIFFIES_TO_MSEC(x)     (x)
	# define MSEC_TO_JIFFIES(x)     (x)

Is not correct.  Look at kernel/sched.c for verification of this :)

Looks like we just messed with our carefully tuned scheduler...

We can blame the following changeset from Ingo:

	ChangeSet 1.1608.6.15 2004/05/10 13:26:09 akpm@xxxxxxxx
	  [PATCH] sched: trivial fixes, cleanups
	  
	  From: Ingo Molnar <mingo@xxxxxxx>
	  
	  The trivial fixes.
	  
	  - added recent trivial bits from Nick's and my patches.
	  - hotplug CPU fix
	  - early init cleanup


thanks,
