I have a ARM926EJ based soc board that is not currently running (and won't?) openwrt. I want to install some of the openwrt compiled binaries and also maybe crosscompile some others. I am familiar with cross compiling from the openwrt toolchain already.
My question is if there is there a router already profiled that is based on that chip that I can select as my target?
Here is the cpuinfo:

# cat /proc/cpuinfo

If there is relevant information that I left out I can post that too.

That does help. thanks.
Let's see if it gets me where I want. I am used to openwrt system so I am trying it this way but I really need to (cross)compile RTL8192CU kernel module for a non-openwrt system...

# insmod /mnt/hdd/bin/rtl/data/lib/modules/3.3.8/rtl8192cu.ko                                                          
rtl8192cu: version magic '3.3.8 mod_unload ARMv5 ' should be '2.6.30.10 preempt mod_unload ARMv5 '                     
insmod: can't insert '/mnt/hdd/bin/rtl/data/lib/modules/3.3.8/rtl8192cu.ko': invalid module format                     
#

this means that I need to use older kernel headers? How can I direct openwrt buildroot for that?
