One of my tenants is company that does this professionally and they cut hundreds of circuit boards a day (all ROHS compliant I belive). Believe it or not their ventilation requirements are not very extensive. Of course they have a CNC machine, high end pneumatics, etc. but even with the "Professional Setup" a good shop vac with a good filter setup close to the area that you are cutting is all that you need. It is best to have the actual shop vac unit (the blowing end) pointing away from your work area. I would invest in a decent filter (not the cheap generic ones) and make sure to keep it clean. The point is to suck up the particles before they even have a chance to enter the air.
Their setup uses a high end CNC machine with the drill bits having a much higher RPM than anything that you are going to use (i.e. it makes more fine particles) and the shop vac is all that they use. I am sure if you would like more details they would be more than happy to help. Their website is: http://www.motherboardgifts.com/
