The raid superblocks are parsed to construct mdX devices and the lvm metadata is parsed to locate lvm logical volumes. So you could say it does construct the LV and mounts the FS. In case of lilo: Lilo only stores a list of blocks where the kernel/initrd are on the device. Afaik each component device of a raid stores the the block numbers for the kernel/initrd on that component device. So no matter which component device boots it will find the kernel/initrd on the same device. The raid1 and lvm are completly circumvented.
