Maybe not the greatest idea.  People seem to be griping about various things
in Ubuntu all the time.  But if you want that....

Of course.  If the kernel has modules for this fakeRAID chip, you'll see both
the fakeRAID and the real disks.  You may need to do something to the real
disks, after all, so the kernel makes those available.  If you really want to
use the fakeRAID, then don't touch the real disks, and just use the fakeRAID. 
If this is just going to be a Linux box, and not dual-boot, you may wish to go
into the fakeRAID controller's BIOS setup/whatever and tell it to leave the
disks alone.  Then you can use Linux softRAID, which may work faster and won't
be tied to that particular motherboard.

The distro doesn't really matter here.  You just need something with a recent
enough kernel.  If Ubuntu 12 can find the fakeRAID, it's almost certain that
CentOS 6 can find it too.
