Hi,
I have patched the omap-aes driver so I can use it as a module on the Nokia N900 (2.6.28).
However cryptsetup does not work with aes-cbc-essiv:rmd256, this locks the cpu and I have to stop it with ctrl-c.

Using cryptsetup with aes-cbc-essiv:rmd128 is successful, but the N900 does not wake up from powersaving, while the module is loaded.
The module compiles without warnings, I have no idea.
