The Gray Screen of Death: another hanging Mac question.

A friend of mine generously gave me her older iBook G4 that she didn't need any more. However, the other day when I tried to turn it on it got to the gray screen with the apple logo and the spinning wheel and hung there. That's as far as I've been able to go since then. Neither my friend nor I are 100% positive what OS it's running, but I'm pretty sure it's 10.4.1. Now, bearing in mind that I'm not terribly competent at fixing computer problems, I've tried what seem to be the standard quick fix ideas and here's what happens:
-Starting in safe mode: it gets to the gray screen, stays there for a minute, then shuts itself down again.
-Resetting the PRAM and NVRAM: no change.
-Starting in verbose mode gets me to this message:
Mounting local filesystems
/dev/diskOs3 on / (local)
kern.sysv.shmmax: -1 -> 4194304
kern.sysv.shmin: -1 -> 1
kern.sysv.shmmni: -1 -> 32
kern.sysv.shmseg: -1 -> 8
kern.sysv.shmall: -1 -> 1024
Resetting files and devices
mkdir: /private/tmp: No such file or directory
and it stops there.
Further complication: the computer originally came with OS 10.3.5 and I have the disks for that. However, as I said before, I'm pretty positive that it is now running something above 10.4 (my friend must have upgraded at some point, but she doesn't remember how or when). The tip sheets that I've seen online all say NOT to use disks with an older OS to attempt fixes. My friend also offered to lend me the disks for her current Mac, which are OS 10.5.2 but I'm not sure if that will help me. My question(s) are, can I potentially use any of these disks to do some sort of diagnosis or fix on the computer? If so, which ones and how (again bearing in mind that I'm pretty clueless about this stuff)? Based on the information given, can you think of any other ideas that might fix this problem? Thanks, folks.
