Unfortunately x64 bit version cannot find this controller. When I use i686 version of Owl I can install system without any problem. Can you help me with this task?

This is puzzling.  On x86_64, we compile CONFIG_FUSION_FC as a module,
but this shouldn't be relevant because your controller appears to be SAS
and not Fibre Channel.  Yet can you try "modprobe mptfc" just in case
and let us know if it makes a difference?

Another guess is that your controller somehow presents itself
differently when initialized by the x86_64 kernel.  Is the above lspci
info from an i686 or a x86_64 boot?

0x0056 is indeed supported in the kernel.

For similar controllers that are unsupported (unlike yours), the recipe
is like this:

mount /sys
echo '0x1000 0x0059' > /sys/bus/pci/drivers/mptsas/new_id &

which gets the controller recognized while CD-booted, and a patch like:

http://bugs.gentoo.org/show_bug.cgi?id=325805
http://bugs.gentoo.org/attachment.cgi?id=236721

to keep it recognized by the new kernel (to be installed).  This worked
for me for a particular MPT Fusion controller type, but like I said it
should probably not be needed for yours.

So let's figure out what's going on in your case.
