OpenBSD with KDE was pretty good, and I would have stayed with that but lucked out and was able to get a clean low-level copy of the old hard drive to a new one using 'dd' and get back to the original system.

I'd go for CentOS in that situation with the Stella repositories for multimedia, but would also consider Debian Wheezy XFCE4. As others have suggested one of the Mint flavours might work well.
Having said that, Debian Wheezy 'full fat' with Gnome 3/Shell works fine on this X60 manufactured in December 2006 and fitted with 1Gb of RAM. Admittedly, that was not a low end machine when it was manufactured.
DE's matter more than the distro when it comes to the amount of resources consumed...
It sounds like the machine may have had additional issues. I ran Ubuntu 7.04 - 12.04 on my 2005 machine until this year and could really have made it another year or two but thought it was time to treat myself to an upgrade.
