Lazy atime mount option?

I have a laptop, and to speed it up and prevent the update daemon from
writing the HD, I have used the "noatime" mount option. However, what I'd
really like is a "lazyatime" write feature:

I figure such a feature would simply *not* toggle the flag that says there
is something flush to the HD when the atime is written to. (Figuring that
if something writes to the HD, then it's put in the cache and a bit-flag
is set to "dirty" or some such.)

I'm not sure if this is reasonable, but I'd rather have late or unreliable
atime setting than no atime setting at all (and none rather than 100% on).

Can someone tell me if this is possible? or would this require major
poking at the cache/buffer code?

Thanks!
