One of the best live Linux CD's out there is the FC8
http://mirrors.kernel.org/fedora/releases/8/Live/
uses the 2.6.23 kernel. Knoppix 5.1 is Jan07 and
kernel 2.6.19
BTW, I hear a lot of negative things about dmraid and
fakeraid. I have an FC5 desktop box dual booting WinXP
and FC5 on fakeraid/Raid0 thats been perfect for over
3 years. That includes a kernel upgrade in FC5, which
required me to run mkinitrd (since it froze during
boot) to get it working.
