The PSP attach rates are in line with GB and GBA attach rates if you go by shipments. DS attach rates are about 30% higher per machine, and the base is twice as big (~100m DS shipped vs. ~50.3m PSP through March 6). Through December there were 536m DS games shipped for 96m DS, so the attach rate is about 5.5. PSP through January when Sony said the systems shipments topped 50m, has an attach rate of four since they claimed 200m games shipped.
With much less time on the market, Wii and PS3 software/hardware shipment rates are about 7 each.
