Roadblock Exploring Installed Modules

As I understand it,  I need to poke around in /sys/module and /system/lib/modules  to figure out what drivers are doing what in my device.

There is no /system/lib/modules directory on my NST.  The /sys/module directory contains the following:

• kernel
• printk
• wakelock
• userwakelock
• earlysuspend
• spurious
• omap3epfb
• keyboard
• vt
• bridgedriver
• scsi_mod
• usbcore
• musb_hdrc
• omap_hdq
• w1_bq27000
• usbhid
• binder
• lowmemorykiller
• snd
• snd_timer
• snd_pcm
• snd_dummy
• oprofile
• tcp_cubic
• rfkill
• pvrsrvkm
• omaplfb
• bc_example
• tiwlan_drv

None of those contains any .ko files.  Using Root Explorer to search for *.ko, finds only these:
/etc/wifi/tiwlan_drv.ko
/system/bin/sgx/omaplfb.ko
/system/bin/sgx/pvrsrvkm.ko

I am trying to figure out how to get modinfo information for these.   XDA Thread    Phandroid Thread
