I knew about these in general, but still good to post as others may not.

You are talking write-caching here.  I generally leave that pretty much 
alone, for the reasons you mention (corruption in case of kernel panic 
and/or power failure).  That's also why I've chosen not to run XFS.  (I 
run reiserfs and while I did have issues some years ago, early kernel 
2.4, I've had none since the introduction of data=ordered journaling and 
that as the default, even when I had faulty memory and was having fairly 
regular kernel panics as a result.  I wouldn't have wanted to try that 
with big write caches and/or XFS!)

The caching I had in mind was read caching.  No risk there. =8^)
