Should I be concerned with burning around 1/3 of a quart after 3,500 miles?
So you're getting 10,500 miles / quart. Based on threads here and other forums that I've read for M52/M54 oil consumption your result is well within the normal/good range for the M54B30 engine in your car.

You may be interested to hear that BMW's TIS specifies "For BMW spark-ignition and diesel engines the maximum permissible oil consumption is 0.7 litres / 1000 km" which converts to 936 miles / quart. For M engines the standard is 1.5 litres / 1000 km, (437 miles / quart) due to their "increased power output and torque" which I take to be the M3, M5, etc. vehicles rather than the M52/M54 series engines.
Not a very difficult standard to meet, is it?
