This is not the right fix. (hint: i8237 is not modified by xen and has
nothing to do with smp)
Unfortunately, properly fixing the bug is not trivial.
basicly linux/smp.h has to be included before xen's system.h get
included for the compilation to succeed. As the i386 kernel
doesn't need this assertion, it's not working for i8237..
I tried a couple of things, but they all lead to some funky errors ..
