  And right you are! Just edit /etc/sysconfig/kernel, add dm-raid4-5 to
  INITRD_MODULES and then run mkinitrd to rebuild the initrd. At the next
  boot dm-raid4-5 will get loaded automatically.

  AFAIK there's no way to directly have grub boot an OS on a software
  RAID5 partition.

I added dm-raid4-5 to the sysconfig kernel file and ran mkinitrd which 
completed fine.
After booting I get the following error in boot.msg:

<6>raid5: automatically using best checksumming function: generic_sse
<4>   generic_sse:  6441.000 MB/sec
<4>raid5: using function: generic_sse (6441.000 MB/sec)
<6>device-mapper: ioctl: 4.11.0-ioctl (2006-10-12) initialised: 
dm-devel@xxxxxxxxxx
<3>dm_raid4_5: Unknown parameter `5'
...
FATAL: Error inserting dm_raid4_5 
(/lib/modules/2.6.22.17-0.1-default/kernel/drivers/md/dm-raid4-5.ko): Unknown 
symbol in module,   or unknown parameter (see dmesg)

If I manually modprobe dm-raid4-5 everything loads fine and I can mount the 
partitions on this array.

It almost looks like "dm-raid4-5" is being parsed as "dm-raid4" with  parameter 
"-5" !! 

Any ideas what might be going on here?

Thanks,

Vahe
