Actually, It went to single user mode on the console (I was logged in 
via serial console).  However, I could not mount anything for some 
reason. Going in /dev, only /dev/ada0 and /dev/ada0s1 were there. The 
disk slices were not for some reason. This was on an AMD64 kernel BTW.

But, going back to the original i386 image, with the boot blocks 
reinstalled and using your latest patch, it seems to work! (however, 
the same 300sec delay due to the cdrom ?  )
