how would I know?

I would think that it would be easier to create a 'USB Pen drive' with a
live cd on your laptop and boot from that but I still think that you
will need to concentrate on file recovery if there are any files that
you need off that hard drive.

Long story short...if the / doesn't at least mount read-only, you have
no chance to repair anything in order to get it to boot up unless/until
you find another way to boot that system or as you say, put the drive
into an external case and connect it to another computer. All of the
various boot parameters you are tossing at grub booting are just a waste
of time.

Obviously if you have the hard drive connected to another booted system
or can boot via a USB pen drive, you can try to repair the unmounted
filesystems (/dev/hda1, /dev/hda3, /dev/hda5) via e2fsck program. The
swap partition is the least of your concerns at this point.
