I'm CC'ing ubuntu-sounder at lists.ubuntu.com, let's please continue this
thread there. This is getting more and more into a chatter than
development discussion.

Sounds very similar to what linux vserver patches provide. [1] The kernels
in debian/unstable seem to already provide such a kernel variant.

Well, from what I understand, they offer (on i386 only) some syscall,
to enable x86 binaries to run on a solaris kernel. Right? Does this mean
you can debootstrap ubuntu 5.10 or ubuntu 6.06 in a solaris brand and
use all functionality? What about tools like iptables, tc and iproute2?
