    Well, Thomas and Simon set up a mercurial repository, but I really
    don't want to try to use yet another repository to work on the driver.
    I would much prefer that it simply be brought into CVS and worked on
    in CVS.  It would simply remain disconnected from the build until 
    it can be made to work.
You don't have to, it can be imported into CVS and have the existing 
patches applied there, and then the remaining work.

    There are only two header files outside of the nata driver code that
    conflict.  The nata driver versions of those header files can simply
    be renamed so as not to conflict.
ata.h has already been renamed nata.h, and I guess you're talking about 
opt_ata.h for the other one, which can be renamed to opt_nata.h without 
too much of a problem. Then the only 'conflict' keeping both drivers 
from being in the same system is that the new ATA driver supports the 
same hardware as the old one besides new hardware it also supports, 
meaning it depends on who attaches first; we could just let config(8) 
bail out as soon as it finds both ata and nata devices in the kernel 
config. Also, it's possible to have both drivers attach only a set of 
devices which don't overlap with eachother. I'm not sure if that's 
something worth having?
