Now that we support ext4 and palo within the boot label, update the
documentation to reflect this. Also beef up the man page with
examples and remove reference to palo in the gnu info system because
it doesn't exist.

+palo is the installation and management tool for the parisc
+bootloader, called iplboot. The size required for the iplboot binary
+is 256kb. Older MS-DOS label disks begin the first partition at
+sector 63 and there is no room for iplboot within the disk label, so
+you must create a palo partition of type F0 to hold iplboot. If your
+disk was formatted more recently it should have a newer MS-DOS label
+where the first partition begins at sector 2048 meaning there is room
+for iplboot within the disk label and a palo (F0) partition is not
+required.
+
+If you have a palo partition (type F0), it must occur within the first
+2GB of the beginning of the disk. If you choose to have a palo
+partition, you may store both the kernel and the initrd in this
+partition, meaning you have to update it every time you update the
+kernel, or you may choose to have a /boot partition, which must be
+formatted as an ext2/3/4 filesystem, from which palo will load
+kernels. This /boot partition also must be within the first 2GB of
+the beginning of the disk. If you have no palo partition, and palo is
+installed inside the disk label, you must have a /boot partition
+because the disk label is still too small to contain a kernel and a
+ramdisk.
+
+Palo allows you to specify a kernel command line, which is stored in
+the firstboot partition. The format should be kernel first followed
+by an optional initrd= and then the rest of the kernel parameters.
+For parisc system, you should specify a boot console as console= on
+the command line. The format of the kernel and initial ramdisk files
+is <partition number>/<path to file>. It is recommended, but not
+required, that both the kernel and the initial ramdisk be in the root
