RHEL/CentOS kickstart partition offset

Because of underlying storage, I need the partitions created by the RHEL/CentOS installer to begin on a multiple of 8 sectors. By default the part command during kickstart (see this page for kickstart reference) offsets them by 63 sectors:

[root@bs-simon ~]# fdisk -lu /dev/sda

Disk /dev/sda: 85.8 GB, 85899345920 bytes
255 heads, 63 sectors/track, 10443 cylinders, total 167772160 sectors
Units = sectors of 1 * 512 = 512 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *          63      160649       80293+  83  Linux
/dev/sda2          160650   166738634    83288992+  83  Linux
/dev/sda3       166738635   167766794      514080   82  Linux swap / Solaris

part does offer --start to specify the starting cylinder, but can someone suggest a way to get part to start on a sector that is a multiple of 8? Or do I just need to give up and partition the disk manually first?

btw, this is to get the linux filesystem blocks to align with underlying VMware VMFS datastore blocks, which align with NetApp LUN blocks.

thanks!!
