Please pardon the cross-posting to centos-users - in case others may be
interested.

Did a fresh install of CentOS-5 x86_64 on my server with Areca RAID (2
5TB RAID-5 arrays) with the OS on mirrored SCSI disks set up as software
RAID-1 using Karanbir's dd ISO image.  Used custom install and mounted
the existing Areca RAID arrays as /data1 and /data2 (as they were for
CentOS-4 - originally set up by the vendor with RHEL-4).  Install and
reboot went flawlessly, but after update to the latest kernel a reboot
did not find the driver for kernel-2.6.18-8.1.8.el5 and left me in
single-user mode.  Copied /lib/modules/2.6.18-8.el5/updates/arcmsr.ko
created by the original installation to 
/lib/modules/2.6.18-8.1.8.el5/weak-updates/arcmsr.ko 
did "depmod -a" and "modprobe arcmsr" and the Areca devices then
mounted.

I'm a newbie to weak-updates so would appreciate it if anyone could
point out the "right way" [TM] to do this automagically when a new
kernel is installed.  Perhaps my google-foo is off today, or I have not
exercised sufficient diligence to RTFM, but can't seem to find the
recipe.

Meanwhile, back at the ranch...

Wanted to try the dkms approach and the spec file below (based on
RPMforge dkms-r1000.spec) worked for me.  Installing the resulting RPM
created /lib/modules/2.6.18-8.1.8.el5/extra/arcmsr.ko, made a soft link
to it as /lib/modules/2.6.18-8.el5/weak-updates/arcmsr.ko, and removed 
/lib/modules/2.6.18-8.1.8.el5/weak-updates/arcmsr.ko

Should probably have figured out how to use the original ZIP archive
from the vendor

ftp://ftp.areca.com.tw/RaidCards/AP_Drivers/Linux/DRIVER/CentOS/CentOS-5.0/1.20.0X.13/arcmsr.redhat.1.20.0x.13.zip

in the spec, but instead cheated and created a .tgz archive from it to
stay closer to the r1000 spec file's approach:

$ tar ztvf arcmsr.redhat.1.20.0x.13.tgz 
drwxrwxr-x prs/prs           0 2006-12-22 17:52:50 arcmsr.redhat.1.20.0x.13/
drwxrwxr-x prs/prs           0 2006-12-22 17:52:50 arcmsr.redhat.1.20.0x.13/arcmsr/
-rw-rw-r-- prs/prs       96956 2006-11-08 16:59:50 arcmsr.redhat.1.20.0x.13/arcmsr/arcmsr.c
-rw-rw-r-- prs/prs      377113 2006-11-08 16:59:00 arcmsr.redhat.1.20.0x.13/arcmsr/arcmsr.h
-rw-rw-r-- prs/prs         149 2005-07-21 19:10:00 arcmsr.redhat.1.20.0x.13/arcmsr/Makefile

Have yet to have a go at packaging the vendor's binary (CLI and HTTP)
files in an RPM (reference earlier nosrc.rpm discussions in this
thread), but did create a chkconfig-compatible script to set up the
httpd service after a manual install.  See below.

I would hope Areca drivers might appear on RPMforge or CentOS Extras
some day soon.  Comments appreciated.
