1) Did you also check the downloaded image's digest before you went and burned another CD?
2) From what (exact) URL did you download the CD image?

no, but I booted the CD also on another notebook (T41), and this notebook booted from it

256MB of RAM isn't very much these days. Also, there was a problem on the 2008.0 LiveCDs with the initramfs being *massive*. I don't recall if that was fixed in -r1.

Boot the CD up on another machine and check the size of /mnt/cdrom/isolinux/gentoo.igz. If it's more than a few MB, that's the problem. You can try using the minimal CD instead.

Closing as we don't provide livecds any more.
