I'm a C1000 owner looking for the "full disto" experience.  I dabbled with OpenBSD, and got it working for a while, but I never got the hang of it.  I went back to pdaX because it offered the closest thing to a desktop environment on a Z.  Debian seems like something to be excited about.  
The standard install method seems to be from the z1000_debian.txt document.  The problem is that I don't want to commit to uboot.  Also, it seems like a much better idea to install debian to a SD card then NAND, just for the extra space.
Does anyone have a method for booting a debian filesystem on SD to share? Maybe Altboot?
