The X-Amiga installer CD is nearly finished, if you can wait a bit longer. (There's a website too...)
The installer only asks for simple things: CPU, graphics card, etc. The Linux installation is taken care of automatically. It now uses tiny X (much smaller than xorg-x11) rather than DirectFB.
I've found booting is incredibly fast - half the time is taken up with the BIOS hardware check.
If you prefer the Windows route, you could try

I'll announce X-Amiga properly as soon as it's finished. Don't want to be accused of anything 'vapour'-related!
