Yup.. it's fairly standard stuff.

I would advice that using it to do more than to ensure DMA is turned
on would be unwise in most cases (unless you have the manual for your
hard disk handy).

Well.. if you're using ext3 you'll have a fully journalled file system
anyway.  ReiserFS is just a different type with a few extra features -
Resier4 is about the fastest filesystem out there right now, but most
distros haven't got support for it yet.

Well, that sounds like a sensible approach.. have fun.
