Please don't omit a relevant mailing list when doing this - by all means CC me 
in, but I don't always have time to answer questions, and including the 
mailing list helps you get a timely answer.

This is very deliberately not possible with the -nocursor option - it aims to 
ensure that the cursor cannot be displayed no matter how hard X applications 
try.

You want to look at the XFixes extension - the -nocursor option simply alters 
the cursor behaviour to act as if a HideCursor request is in force for all 
possible windows.
