hdparm init.d script?

["Thomas Chadwick" <j_tetazoo@hotmail.com>]

I recently discovered that I can greatly improve my harddrive performance by 
customizing a few settings using hdparm on the command-line.  I'd like to 
make the changes permanent, but I'm not sure where to do that.  Is there an 
/etc/init.d/hdparm script out there somewhere that I should be using?  
Presumably I'll want to link to it from one of the /etc/rc*.d directories.  
Which one, and what should I call it?
