Installer fails on fakeraid / dmraid hardware

Mint 9 / AMD64 / Gnome.

Issue 1
======
The installer can not complete installation of Mint 9 on fakeraid / dmraid system on AMD motherboard set to raid 1. After running through the installer right to the end the error given reports that partitioning failed, but no clear reason is given.

Issue 2 (Very Probably Related To Issue 1)
======
As another issue which is probably (but not proven to be) related, partitioning manually with gparted from the installer fails. To recreate this:

1) Run mint amd64 installer CD and boot into Gnome.
2) Don't use the installer yet, as partitioning will fail (maybe for the same reason?)
3) gksu gparted /dev/mapper/pdc_caafahgcei # <-- this is my fakeraid logical device.
4) make a partition and apply

Why Does it Fails
==============
The errors given by GParted clearly show the problem.
GParted expects first partition of /dev/pdc_caafahgcei to be called /dev/mapper/pdc_caafahgcei1, but "ls /dev/mapper/" shows that it is called /dev/mapper/pdc_caafahgceip1 (note the 'p' before the '1').

After discussing this with the author of dmraid, it seems that this is likely due the dmraid being called thus by the installer:
dmraid ... -Pp ...

Workaround To Both Issues
======================
Running "dmraid -tay -d -vvv" reloads dmraid, which makes new devices /dev/mapper/pdc_caafahgcei1, /dev/mapper/pdc_caafahgcei2 etc which gparted can then see. As a bonus, it is then possible to run the installer, which will now find the hard drives so it can install the OS.

I attach the details of my correspondence with the author of dmraid.

Thank you for you efforts,
