The current opensource kernel state has no support for some periferals so I suppose that just like me people are looking for multiboot that would allow to run ubuntu and android.
There is a way to get 10.10 running from external storage (but 10.10 for AC100 is unstable and often crashes while browsing)
Natty (with more recent kernel) can only be installed on internal storage replacing android or at least replacing the android kernel image which makes android unusable anyway.
Uboot is still experimental for AC100.

This leaves currently no way to have true multiboot for AC100.

I've an idea on how one could go about getting true multiboot for AC100:
Replace partition 5 with a modified tegra-2.6.29-arm2-ac100-boot.img that would include a kexec enabled kernel and a kexecboot initrd

This would let you boot android normally while letting you easyly boot a generic distro off external storage instead of the flash mode boot.
