I checked the block size of the generated logical volume after using the YaST partitioner by looking in /var/log/YaST2/storage in the file 04-committed.xml. Also all the relevant calls in Lvm{Vg/Lv} seem to use the ULL_HACK. Surely there could still be problems with AutoYaST. But for that the autoinst.xml file and the complete YaST logs are needed.
