I finally got it to work.  The drivers were not being installed even on 
with testsigning on (didn't seem to make a difference).  I installed the 
drivers, got a warning but told it to ignore it, but the drivers were 
still not showing up as installed in device manager.  I think installed 
them manually through the device manager before rebooting and then set 
up the boot entries.  This made it work, but the performance seems 
pretty bad.  Originally I was averaging around 70mb/s on a system that 
does about 340 MB/s as measured by hdparm -t.  After installing the 
drivers, I'm not averaging 18MB/s.  Did I do something wrong?  I though 
these drivers were supposed to give better performance, not worse? 

This is my disk line if it helps:

disk = [ 'phy:/dev/mapper/VolGroup00-lvol2,hda,w', 
'file:/mnt/isos/en_windows_server_2008_datacenter_enterprise_standard_x86_dvd_X14-26710.iso,ioemu:hdc:cdrom,r']
