You want PNG32 export instead of PNG24? Do any save/export formats save
a 32bit image? If so you may be able to convert afterwards. If not it
looks like the file save engine is not built for it.
Perhaps SVG support in Inkscape is more in line with what you want. It
also has PNG export (which i have not tested to see if it is PNG32).

You might want to look at and perhaps even make comments about the work
going on with the Enhanced Graphics Export extension. Currently it is
only doing 24bit also for png, but may support 32 in the future - asking
for that now while it is being designed and built might help make that
happen.
You can find information about it and a beta of the current work for
review in this issue, and a discussion on the UX mailing list.
