USB keyboard driver the GNU Mach

This does not seem like the right forum for this post, but this list looks like the only hurd list with any activity, so here goes.

I have taken on the project this year of getting the hurd running on an oldish PC on bare metal. The first issue I encountered is that the PC does not have a PS/2 port and the BIOS does not seem of offer any emulation. GNU Mach does have any support for usb as far as I could tell.

I have worked to re-purpose some old (2.4.x) Linux kernel usb code to produce a basic usb keyboard driver for GNU Mach. It is a bit more than a key board driver. It is a usb hardware controller driver (UHCI only for now) with the ability to handle the control messages and interrupt messages needed for a HID keyboard. It is far from a full-blown usb bus subsystem, but it is functional, and I have gotten the Hurd running on the PC with a keyboard (it can actually handle 4 keyboards :)).

So my question is, would any others be interested in working with me on this project, and how should I go about submitting it for code review or inclusion in the source tree? I could use some help on integrating the keyboard driver with the console. I have hacked it into kd for now, but I am sure it could be done more elegantly. I also am not sure if my memory manipulation in the kernel is properly done.
