Bug#515990: debian-installer: Fails to detect partitions on hard disk

[Mark Brown <broonie@debian.org>]

Package: debian-installer
Version: 5.0
Severity: important

When attempting to install on my Dell XPS M1330 partitioning correctly
detects my disk but only offers me the option of creating an entirely
new partition table (either manually or via guided install).  It does
not offer me the ability to use or modify my existing partitions.

The kernel and fdisk both recognise the partitions, fdisk reporting
the partition table as:

Disk /dev/sda: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x28000000

Partition table entries are not in disk order
