Nokia N900: omap aes is broken

I tried to test OMAP AES driver on Nokia N900 with special Nokia
bootloader which enable L3 firewall for OMAP AES HW support.

I modified arch/arm/boot/dts/omap34xx-hs.dtsi file and commented
aes line which disable aes support in DT.

Then I booted kernel and loaded omap-aes.ko module. And I got
this output in dmesg:

[ 0.222930] platform 480c5000.aes: Cannot lookup hwmod 'aes'
[ 27.758148] omap-aes 480c5000.aes: _od_fail_runtime_resume:
FIXME: missing hwmod/omap_dev info
[ 27.765960] omap-aes 480c5000.aes: omap_aes_probe: failed to
[ 29.257690] omap-aes 480c5000.aes: initialization failed.

So it looks like some initialization data are missing for Nokia
N900 (omap3430 device).

Can somebody look at it? I have patched 2.6.28 kernel were omap
aes support on this N900 device (with special bootloader) is

Maybe some other data are missing in DT or in hwmod?
