@colin.stephane - ok, ramzswap seems to work, but it has statistics enabled, will you please consider downloading compcache.zip again and checking all the modifications. In latest Makefile from the above .zip statistics are disabled (for performance reasons). I have also add some #ifdefs in ramzswap_drv.c file. And please, upload .diif file here, so I can add it to my kernel tree and check what is going on, ok?

Thanks
