[Fedora-xen] fedora7 xen questions

Hi, I am using Fedora7 xen kernel version: kernel-xen-2.6.20-2925.11.fc7 and my xen version is: xen-3.1.0-2.fc7 and I am experiencing two difficulties. First is that my wireless network card is not working (intel 3945 a/b/g). I am using ipw3945 driver. It is loaded as a module when I check via lsmod. But /sbin/ipw3945d says: No Intel Pro/Wireless Device Found. It works perfectly with the non-xen kernel that is: 2.6.21-1.3228.fc7 The next thing that annoys me is that when I shut down the machine with the xen kernel it does stops all the process and at last shows my "System Halted" and it stays right there. Doesn't really shut it down. With the non-xen kernel I don't have any such problem. So are these problems are a unknown bugs ? And what steps do I need to take to eradicate these problems.
