I agree, it would be nicer if we don't introduce a special flag
just for that. Other than that, I like all sane code that speeds up
suspend/resume :). I've attached before/after dmesg excerpts on my
system with the patch ontop of v2.6.37-rc2-181-gb86db47. We end up
saving 11601 µsecs according to CONFIG_PRINTK_TIME but hey, the code is
simple enough :).

Thanks.
