If your driver supports it, you can display a cursor using the 
standard int 0x33 functions: see Ralph Brown's interrupt list eg. 
http://www.delorie.com/djgpp/doc/rbinter/ix/33/00.html.

Maybe you will be lucky and this will work ok on your machine, but
I rather doubt it (in my experience only about 5% of mose drivers 
know about SVGA modes). If you want other people to be able to run
your program, stay away from this.

It's possible that you might be able to find a different mouse driver
that works better than the one you are currently using, but that also
isn't a good solution for general use because different mouse hardware
requires different driver software, and not everyone will want to
reconfigure their machine just to run your program. So even if you are
able to get this working for you, it won't be a general solution for
the problem on other machines as well.

Am I allowed to plug Allegro again here? If you don't want to do this
work yourself, I've already done it all for you...
