[CentOS] SiI 3114 and RAID

I've two machines with almost identical hardware (slightly different 
CPUs). The SATA/RAID controller is SiI 3114.

One of the servers was installed a while ago by someone else, it's 
running Fedora Core 5 and RAID is enabled:

# df -m
Filesystem           1M-blocks      Used Available Use% Mounted on
/dev/dm-6               125931      2990    116441   3% /
/dev/dm-1                   99        13        81  14% /boot
tmpfs                     1012         0      1012   0% /dev/shm
/dev/dm-2                 9917       151      9254   2% /tmp
/dev/dm-3                 9917       237      9168   3% /var
# cat /etc/modprobe.conf | tail -n 1
alias scsi_hostadapter sata_sil

I installed CentOS 4.4 64bit on the other system, but I could not enable 
RAID. The installer was always seeing 2 separate drives instead of one 
RAID device.

Was it my mistake? Did I not enable the proper settings in the BIOS? (I 
tried quite a few different settings)

Or is it perhaps that the CentOS kernel does not have the proper drivers 
to support SiI 3114 in RAID mode?
