I'm using Fedora Core 5 x86_64 with qemu 0.8.2 and I have noticed these 
warnings as well. However, they do not seem to be a problem, at least 
for what I'm currently doing, developing a new system on top of qemu. 
They seem to be casts from "void *" to "int", which is OK on x86 but 
generate a warning on x86_64 since sizeof(void *) != sizeof(int) on that 
platform.

I other words, I doubt that these warnings are the source of the problem.
