Is there any way to tweak what Superfetch loads or when?

My goal would be to either control what it loads to avoid infrequently
used data files from being loaded, or to turn it off entirely on battery
power.

Don't get me wrong, I like the idea of Superfetch, but I'm running into
a case where I see Superfetch loading 100MB+ video files and a whole
chunk of my media library and whatnot into memory for 5-8 minutes after
I boot up, this is just killing my laptop's battery life since it's
driving two 7200rpm drives as hard as possible for several minutes
whereas the drives would otherwise be idle and one might even spin down.

In practice I'm measuring about a 20-30 minute loss of over-all battery
life if I disable Superfetch entirely and fire up my laptop in the
airport to do light email/newsgroup/etc -- I'm not measuring real
scientifically here, just based on my actual use after several flights
with a variety of stop-overs and several tests in a row at home.

When I'm on battery I'll take extended battery life over performance any
time, any suggestions on how to accomplish this?

Hell Dave,

These two tutorials can show you how to tweak Superfetch to either
disable it, or to have Superfetch to preload only the Boot files,
Program files, or the default both Boot and Program files into memory.

Hope this helps,

I was hoping for a bit more granularity, I suspect I'd be happy with
loading boot and program files but not data files, for example, but
there doesn't seem to be anything like that available.

At this point I'm thinking I'll just push out a group policy for
portable PCs to set them to Boot-only and give up Superfetch's benefits
when it would be appropriate to use it.

Thanks.
