I rewrote the CC to bug-hurd@gnu.org, which is the most appropriate list.

Whatever works. :-)  

The existing IDE drivers used in gnumach are taken from Linux-2.0.x.
You can modify those or try to drop a new Linux version in.

You might also consider trying oskit-mach, which gets its drivers from the
OSKit.  The OSKit currently has IDE drivers from Linux-2.2.12, and it is
pretty easy to drop newer Linux-2.2.x drivers into the OSKit source tree.
