Now we need support in ubiquity to have ext4 support.
AFAIK ubiquity uses debian-installer code as well as libparted.
Now dunno how much support is there or needed in debian-installer but seems to have some initial support in libparted.
I guess we get it as and when libparted 1.8.9 is done.
The libparted version which we have is seems to be 1.8.8.git.2008.03.24-11.1ubuntu1

Description: The GNU Parted disk partitioning shared library
GNU Parted is a program that allows you to create, destroy, resize, move and copy hard disk
partitions. This is useful for creating space for new operating systems, reorganising disk
usage, and copying data to new hard disks. This package contains the Parted binary and manual
This package contains libparted, the required shared library used by Parted.
Parted currently supports DOS, Mac, Sun, BSD, GPT, MIPS and PC98 disklabels/partition tables, as
well as a 'loop' (raw disk) type which allows use on RAID/LVM. Filesystems which are currently
fully supported are ext2, ext3, fat (FAT16 and FAT32), ReiserFS (with libreiserfs) and
linux-swap. Parted can also detect and remove HFS (Mac OS), JFS, NTFS, UFS (Sun and HP), XFS and
ASFS/AFFS/APFS (Amiga) filesystems, but cannot create, resize or check these filesystems yet.
Note that ReiserFS support is only enabled if you install the libreiserfs0.3-0 package. Since
libreiserfs0.3-0 has been removed from sarge, ReiserFS support is not compiled in the default
