Loss of ed(4) in a RC1 booted in qemu

Hello,

I have booted the latest RC1 boot only iso image from qemu, and it seems we 
have lost the attachment to ed(4) :
% qemu -boot d -cdrom 6.0-RC1-i386-bootonly.iso -serial stdio 6.0-RC1.img
OK boot -v

the ed device is correctly detected and attached in the same conditions from 
the BETA5 boot-only image :
