fwiw, no problem here with the before-last kernel:
[root at tryo nthierry]# uname -a
Linux tryo.imag.fr 2.6.18-164.9.1.el5 #1 SMP Tue Dec 15 20:57:57 EST
2009 x86_64 x86_64 x86_64 GNU/Linux
[root at tryo nthierry]# modprobe --first-time ipt_recent
[root at tryo nthierry]# lsmod | grep ipt_recent
ipt_recent 42969 0
x_tables 50505 5
ipt_recent,ipt_REJECT,xt_state,xt_tcpudp,ip_tables
And also no problem with the latest kernel:
[after a reboot to 2.6.18-164.10.1.el5]
[root at tryo nthierry]# uname -a
Linux tryo.imag.fr 2.6.18-164.10.1.el5 #1 SMP Thu Jan 7 19:54:26 EST
2010 x86_64 x86_64 x86_64 GNU/Linux
[root at tryo nthierry]# modprobe --first-time ipt_recent
[root at tryo nthierry]# lsmod ipt_recent
Usage: lsmod
[root at tryo nthierry]# lsmod | grep ipt_recent
ipt_recent 42969 0
x_tables 50505 5
ipt_recent,ipt_REJECT,xt_state,xt_tcpudp,ip_tables
what's your kernel?
did you reboot after upgrading?
modprobe is trying to insert the 2.6.18-164.9.1.el5 module, but you
mentioned the latest kernel upgrade (which is 164-10.1)
