Yes. If you put one disk on each ide channel/adapter/whatever and if you put swap partitions on each drive, you will get a speedup as the kernel is able to use both partitions concurrently (up to a point). You can get even a greater speedup, if you use RAID0 (See package mdutils). Startup of emacs is ~5-10 secs faster on my system, since I converted my /usr partition (using cp -a).
