Perc 6/e, megacli and new linux kernels

Greetings.

I have a problem with megacli and newer kernels with raid controller PERC 6/e.

I use megacli for monitoring raid and disk status. After upgrading linux kernel
to version >= 2.6.28 (currently i used 2.6.31-11, but i've the same situation
under 2.6.28), megacli can't find any adapters. As far as no sources of megacli
available, it's very hard to track where the problem is. I suppose that megacli
fails to find any adapters because of restructuring sysfs in newer kernels, but
it's just a guess, which i can't surely approve.

I've tried different versions of megacli 1.01.24 and 2.0.15, neither of it can't
find perc controller.

Raid array by it self works fine with all kernels i've tested.

Here some usefull information:

with kernel 2.6.24-23 (custom builded from ubuntu repository) everything works fine
