The README files says:

"The install script will install the hpahcisr loadable
object modules into the /lib/modules directory for each kernel
for which a driver object module is present in this package and
exists on the system.  Then it will make a new initrd 
(initial RAM disk) image for the running kernel, if a driver for
the running kernel was installed.  Then, it will update the LILO
or GRUB configuration, as directed, adding a new entry to use the
new initrd image.  If there were already hpahcisr loadable
object modules present in the kernel libraries, these will be backed
up under /use/src/HP/driver_backup."

"driver object module is present in this package" =>
$ find . | grep ko | awk -F/ ' { print $4 } ' | sort
...
2.6.18-194.el5
2.6.18-194.el5PAE
2.6.18-194.el5xen
...

Maybe run once more the install script but, if your kernel version is not 
listed, I do not know if it will help...
Or, maybe you could copy the module in /lib/modules/... and make the initrd by 
hand and hope it works...
Or just disable the "fake" hardware RAID and use software RAID (I am afraid of 
cheap raid)...
