This looks like another problem with the header files.  V0.3 was 
compiled some time ago when the header files were different. If we 
recompile it using latest header files, it won't work on old versions of 
Solaris. That's the problem.

As a nexus driver, cardbus has to use some private header files internal 
to DDI implementation. While these files change over time, we've been 
trying to adapt to the changes by adding private versions of the header 
files in v0.3. That's why v0.3, as a downloadable version, has been 
working fine on S10, S10updates and S11. But it's hard to keep up the 
good "hack" work.

I would recommend latest Nevada, or wait until the cardbus driver goes 
into s10update.

Public interfaces are stable, and the related header files seldom 
change. The problem usually happens to nexus drivers, seldom to leaf 
drivers.
