I believe your success where others have failed is most likely due to
language choice. As a driver, I don't imagine you used C++ at all,
right? The C++ ABI changed completely between gcc 3.1 and gcc 3.3.
Was your pref pane entirely Obj-C?
Did you use any STL or other C++-specific features? Did you fall back
to an earlier gcc version (3.1 or 2.95)?
I'm guessing that if you used gcc 3.3 then any gcc-specific headers
that you included hadn't changed from OSX 10.1 through OSX 10.3.
Although, I'm a bit curious as to which libgcc.a got linked in for your
10.1 project, amongst others.
The last word I had from the compiler team was that 10.1 compatibility
using gcc 3.3 on C++ code is not possible right now as the gcc 3.3
ABI-compatible libraries don't exist which are compatible with 10.1.
You can see this for yourself by examining the usr/include/gcc/ branch
of the SDK for 10.1: there is no gcc3.3 subtree.

I have to say, as painful as our driver was, the pref pane was totally
painless (no pun intended). Put it together fresh, built it, ran it on
10.1.5, 10.2.6 and 10.3.0. Good job, Apple.

We have successfully build a (very) complex driver with 10.3 (and the

SDK) and gotten it to run under 10.1.5. It took us 5 man days to
figure it
out, but we made it.
