If this is a late 2006 machine, it appears it might be 64bit capable, but with a 32bit UEFI bootloader. I found a list of A1181 related specifications from which you might be able to glean more info.
If it is 64bit capable you could try Lite 5.x (5.6 as I write this) which I've successfully used on an Intel Atom based laptop with a 32bit UEFI. I know nothing about installing Linux on Macs but there are some threads findable with Google with some of the necessary information suggesting it should be possible (I tried "macbook a1181 linux" for a quick look). If it is 32bit only, you'd best look at a distro that still has 32bit installers with the XFce desktop (e.g. Debian, MX Linux & Mageia seem to have recent releases).
If you can get Linux installed your biggest performance limitation will be the internal hard drive; an SSD upgrade will make the machine much more usable. Maxing out the installed memory will help too, but 1.5GB of RAM can work ok for light use (email, browsing with only a few tabs open etc) - the Atom laptop mentioned above has similar CPU core performance to your machine (4 cores rather than 2 though) and runs fine for light use with 2GB of RAM and eMMC storage (akin to a slow SSD but still faster than a spinning platter drive).
