Subject: cdrom config change break HVM reboot

Hi Christian,
In cset 10921 "Use xenstore to configure ioemu block devices", a empty cdrom entry is added in /etc/xen/xmexample.hvm:
disk = [ 'file:/var/images/min-el3-i386.img,hda,w', ',hdc:cdrom,r' ]
this actually breaks the HVM reboot in ia32e, since the UNAME of cdrom entry is None and control panel reboot logic can not handle this.
When I try the following config, the reboot works.
disk = [ 'file:/var/images/min-el3-i386.img,hda,w', 'file:/var/image/cdrom.iso,hdc:cdrom,r' ]
Per my understanding, when user want to use cdrom, they should specify a physical ISO file or device, a empty cdrom entry is not valid. So I suggest the follwing simple patch, how do you think?
