Q: Can I use DraftSight or Bricscad V11 with Debian 6 "Squeeze" ?
A: Of course. Debian is an excellent distro and works well with these CAD packages. The screenshots below show DraftSight and Bricscad V11 running on Debian 6 "Squeeze" 32bit in a VirtualBox installation.

Tip: If you want to use Debian 6 as a CAD workstation for professional use you will probably need a more modern web browser. You can try Chrome or ,better, install Iceweasel (Firefox) 4 by following these instructions.
