I fully agree. The same also applies to rt2800pci SoCs (rt305x) which are working quite good already (in terms of WiFi) but also show more CPU usage then the legacy drivers. IMO it would really make sense to work on improving rt2x00 & mac80211 instead of putting much work in a maybe-better-behaving but unmaintainable driver. For example you could start by profiling rt61pci (if your platform supports perf counters) to see if you can find any obvious bottlenecks.
