In this case there is very little I can do. I have done multiple squeeze installs with RAID, and upgrades, and I have not seen this problem. Unless you can reproduce this bug, I cannot do anything but keep this report open.
i've just reproduced such a failing install inside a KVM. see (combined) screenshot attached from first boot.i've snapshotted the VM at different stages and can provide you with one that just boots for the first time (snapshot3, see screenshot).
tell me if you're interrested in investigating it. here's a log of what i did:booted http://cdimage.debian.org/debian-cd/current-live/amd64/iso-hybrid/debian-live-6.0.2-amd64-rescue.iso (sha1=0e5d9409719e657de4cbd9f355545cdc4c869038)
