Hi, I've been wondering about this for a while now. I have been using Gentoo for several years now and have been pretty happy with the results/performance. I've even gone to the extent of making my own livecd for my msi-1036 laptop. Mine was extremely minimal (space constraints on webserver) and I obviously don't have the level of experience that you guys have here.
I have all of the source code, up to the latest version. However, building/adding to a livecd of this magnitude is way over my head. I noticed also that you include the nvidia and ati binary code on your dvd, so I was wondering how hard it would be to add this kernel module. It is used in several LG laptops and at least one by MSI. It would be pretty cool to have a working and useable livecd that can make use of the hardware.
PS, Really like the dvd. Nice work!
