I have compiled a modified version of 'crash.ko' on 2.6.20 and now 'ps -a' works fine indeed. It is interesting that earlier versions of Ubuntu (e.g. with kernel 2.6.15) did not let me use 'crash' without /dev/crash at all - so I had to install crash.ko. Then after upgrade to Ubuntu/feisty I have found that everything works fine with /dev/mem...until I tried the new 'ps -a' command.
