ok. with 3.4.7:

hangover:~# disklist=sda setup-storage 
setup-harddisks is running in test-only mode
Starting setup-storage 1.3
Using config file: /var/lib/fai/config/disk_config/THINKPAD

Preserved partition /dev/sda2 does not end at a cylinder boundary, parted may fail to restore the partition!
Insufficient space available for partition /dev/sda5

with 4.0~beta2+experimental61:

Previous partitions overflow begin of preserved partition /dev/sda2

FYI:

For this listing I'll assume that geometry.
