I use reiserfs on my Gentoo. After a few power problems and crashes it still chugs along fine.
Ext3 and reiserfs are safe though. I would recommend that you use ext2 or ext3 for the /boot though. I read that sometimes there can be a problem with mounting the /boot if it is reiserfs when it first starts to boot and is looking for the kernel. Never had it but why ask for trouble.
I have a how to guide in the answers section if you need something to help guide you through the install.
