Disable LVM in FC5

[Hadders]

Hi all,
  I have a RAID 1 container running through the Intel RAID chipset via 
dmraid etc...

When I boot up I notice Logical Volume management at the start erroring 
against /dev/sda and /dev/sdb (which are part of my RAID) array.
Loading system-config-lvm doesn't help me, and I'm not sure where to 
look to configure this to ignore those disks, or simply turn it off.

Thanks.  Hadders
