Bring back lx brand?

It is hard to say why the BrandZ code was removed from the OpenSolaris. However this can be corrected. With small fixes I've now got CentOS running in a zone on Illumos:

The Illumos Project SunOS 5.11 illumos-gate June 2011
root@indy:~# zoneadm -z centos boot; zlogin -C centos
[Connected to zone 'centos' console]
Welcome to CentOS

Kernel 2.4.21 on an i686

centos login: root

Welcome to your shiny new Linux zone.

- The root password is 'root'. Please change it immediately.
