setting up raid partitions takes very long and installer shows no progress bar for it

Bug Description
Binary package hint: debian-installer
Version Info: 6.06.1 alternate install cd choosing "text install"
I set up a RAID1 system.
First I configured the partitions. (3 identical partitions on two disks).
Then I created the md devices, everything went fine.
BUT:
After finishing up the partition part of the installer the user just sees an empty blue screen while in the background the newly created RAID partitions are synced (cat /proc/mdstat for progress information).
I think this information should be used to display a progress bar. In my case (2x160 gb disk) it took 10-15 minutes. The users are likely to think that the installer hangs and probably reboot.

Users have thought that it's doing nothing and hung... me!
I spent several days time cursing at the machine because it couldn't get the RAID setup correctly when all that was wrong were three things:
1. I wasn't familiar with the installer.
2. The set of partitions I have just so happens to be such that the "Guided Install" and "Help" options stay unmoved when I add raid partitions. The "Configure RAID" option is just out of view. If people leave the partition screen before using that option, the next screen is not very helpful, warning you that you have no "/" mount point, etc. If it had mentioned the option that seemed invisible (and they don't mention that you have to scroll up anywhere) it would have saved me at least a day. The screen never jumped, and I never thought to scroll UP.
3. If you get a RAID half-installed, you have to (at least I did) use the live CD, apt-get mdadm, and then umount, stop the raid, and zero the superblocks to get rid of it. I think the installer disk automounts the raid (my guess) because it won't let you delete a RAID successfully once you've rebooted once. It only works while you're setting the RAID up on that boot cycle.
