it does ... that was over a nfs root. I plan on taking a look at the compiler
warnings here shortly. But I have not tested out how much works on the C200+
with a 64-bit kernel ... I have no idea if scsi works, etc. I will play with
it more and see what is br0k3n.... I was just happy to see the login prompt.

I'm not sure if I understand the question, so let me try to restate the
question I think you are asking.
If you compile in 32-bit wrapper support into a 64-bit kernel ... can
the same kernel be used on a PAT PDC box like the A500?
No. When I first started down the 32-bit wrapper support, I was going
to make the wrappers smart and use the 32-bit wrappers when needed. I
was talked out of the idea, because on all the boxes that need the
32-bit wrappers do not support > 4G ram, thus there is no advantage
(yes Grant, I know ... some application do benefit from 64-bit kernels)
for running a 64-bit kernel on them. The PDC wrappers are designed to
be used for developement/testing purposes for people with these systems.
(By Making the wrappers a compile time option, it saves an additional
level of indirection for every pdc call).
That help? If not, I'll try again.
