Sorry for digging out this old thread. I've just hit the same problem.

Is it a limitation of PyQt bindings or Qt itself? Is there any
workaround available (at PyQt level or above)?

I can't believe this to be a dead end situation - what's the point of
having a mechanism for switching the cursor if there is no way to
modify it? This seems to be a pretty general issue, potentially
affecting many other Qt classes as well.

As Aaron has pointed out, an alternative would be to rewrite the whole
event handling procedure, which is hardly a solution.
