elrepo's mantis doesn't send me a verification mail after signing up. Therefore 
over this channel (instead http://elrepo.org/bugs/view.php?id=541):

I took a look at my EL5 workstation with a 3.2 kernel and generated 
a patch file (not test with a 3.10 kernel):

http://pastebin.centos.org/14751/raw/    (pastboard will survive 1 month)

MD5: rr174x-linux-src-v2.4-1.1.patch = 6642a29737a71962ac20724a4f95cca7

Following process ends up with a compiled module:

# cat /etc/redhat-release 
CentOS release 5.11 (Final)

# rpm -qa |grep kernel-lt
kernel-lt-headers-3.2.65-1.el5.elrepo
kernel-lt-devel-3.2.65-1.el5.elrepo
kernel-lt-3.2.65-1.el5.elrepo

# tar zxf rr174x-linux-src-v2.4-091009-1434.tar.gz
# cd  rr174x-linux-src-v2.4
# cat ../rr174x-linux-src-v2.4-1.1.patch | patch -p0 -b
# cd product/rr1740pm/linux/
# make KERNELDIR=/lib/modules/3.2.65-1.el5.elrepo/build/
# echo $?
0

# # i do not use install.sh, therefore not patched
# cp rr174x.ko /lib/modules/3.2.65-1.el5.elrepo/kernel/drivers/scsi/rr174x.ko
# chmod 744 /lib/modules/3.2.65-1.el5.elrepo/kernel/drivers/scsi/rr174x.ko
# depmod -a 3.2.65-1.el5.elrepo
# depmod -aeF "/boot/System.map-3.2.65-1.el5.elrepo" "3.2.65-1.el5.elrepo"
# mv /boot/initrd-3.2.65-1.el5.elrepo.img  /boot/initrd-3.2.65-1.el5.elrepo.img.$(date +%s)
# mkinitrd  /boot/initrd-3.2.65-1.el5.elrepo.img 3.2.65-1.el5.elrepo

# cat /etc/modprobe.d/blacklist-sata
blacklist sata_mv

# reboot



Unfortunately I can't do some tests on real controllers 
because all workstations I have are in production state. 
So, I actually haven't boot such kernel on my systems 
with harddisks attached. Conclusion, no warranty - only 
for testing purposes! Maybe some one have more knowledge 
to verify this module - at least, it boots fine so far:

# cat /proc/scsi/rr174x/6 
RocketRAID 174x controller driver v2.4 (Dec 25 2014 13:06:41)

Controller 1: RocketRAID 174x/2210 Controller
