UPDATE:(2-29-2008) please add a video or audio recording of your start-up if possible when reporting.
Also, the cold start issues have nothing to do with stalling or fuel pumps. This is strictly related to the upper valve train on the MINI engine. Please be sure to listen to the videos in the links provided above.

Cooper S, 6-Speed Manual
Build Date: October 2007
Miles: 3500+
Duration: 30 seconds to 1 minute
Frequency: has only happend two times.
RPM range: 1500-2000rpm
Ambient Temp: low 30's first time, 18 degrees second time.
Oil: Factory Fill, Castrol 5w-30, oil level full
Any other relevant information:
Car parked with the nose of the car in a downward slope both times. The sound can best be described as a growling, clattering, or rhythmic tapping. This cannot be piston slap at this speed because the frequency is too low. At 2000rpm, piston slap would would happen over 33 times a second. This is valve train related for sure due to the half-speed frequency of the sound. This means that at an engine speed of 2000rpm, the cams are spinning at 1000rpm or roughly 16 times a second.
Changed oil at +4500 miles to Castrol 0w-30 oil (A3/B3 BMW LL-01 specs) Engine runs much quiter in the mornings. There has been no hint of cold start rattle since oil change.
