Mac OS 9 Development Requests (OS Level Items)

The following thread was started to gauge interest in updates to various parts of OS 9.
There has been a lot of great input from many.

As I'm starting to get to a point where I can even start to develop some basic functionality I need to get a better idea of needs/requests.
I can not guarantee any of this will be implemented but I would like the input.
Once I've gotten these requests I will make a poll so that you can vote on what would be most important and I will use that come up with a development road plan.

This thread is for requests that are os level updates.

Here are some examples of OS Level items.
Support for newer logic board chipsets/controllers
New bus architectures (PCI-E, Firewire 800, USB 2)
Improved memory management
Better Multi-tasking
Low level drivers required for boot.
Pretty much anything that would belong in the Toolbox or System folder.
