would the hard drive address space problem be in hurd or mach? All I know about L4 at this point is that it is much more modern, so I wouldnt expect the hurd/l4 system would have that problem.
Mach doesn't do any device drivers per-say, and certainly doesn't have the concepts to manage disk I/O and stuff. However, it does encouraging using memory mapping for a lot of things, so tends to encourage this kind of design. However, memmory mapping the disk drive isn't as far-fetched or bad of an idea as it might sound. Linux essentially does this already, although in a complicated manner because of the address space limit. With a 64-bit architecture, just memory mapping the harddrive can be an excellent way to implement a filesystem.
