This won't work as fastcgi_pass will be inherited into if().  You 
should use internal redirect instead.  Also it's a good idea to 
use geo module for ip checks.  So something like this should 
work:

    geo $static {
        default     0;
        x.x.x.x/32  1;
        y.y.y.y/32  1;
        z.z.z.z/32  1;
    }

    server {
        ...

        location / {
            if ($static) {
                rewrite ^ /static/ last;
            }
            ...
        }

        location /static/ {
            internal;
            alias /disk0/vhosts/blank/;
        }

        ...
    }
