As far as I know you can pass a parameter, but even so, it won't be able to
allocate more than 512MB.
I can compile the VM for you with this change in 5 minutes. But I am not
sure that such simple code would make it work. I think such limit is there
because of something. Otherwise, it sounds stupid imposing a limit just
because.

The problem is that I cannot recompile the VM because I have no access to a

I don't think so, but start cc'ing the VM mailing list. You'd probably
receive more help.
