Your problems sound suspiciously like some kind of hardware conflict--bad RAM or a peripheral Tiger just doesn't like--but it's always hard to tell. I tend to start clean then add possible causes of trouble until I run into the issue.
In my case, though this isn't likely to be of much help, I've had Tiger running quite happily on a 1st gen DP G5, but it so happens that I went all-out with the clean install process. Here's what I did when upgrading:
1) Complete backup of 10.3, wiped the drive, installed a totally fresh copy of Tiger.
2) Allowed the migration thingy to move over my users (only), although that ended up choking on my main useer and not copying anything for some reason.
3) As such, I manually copied all my user data, but from that user's Library folder I ONLY copied the prefs and handful of items I was positive I needed (Mail stuff, for example). Anything else, I figured I'd re-set or re-install, if there were problems.
4) I then reinstalled all pertinent apps from the original installers instead of copying over, just to make sure everything was as it should be and I had the latest versions. As always, though, I avoided any system extensions that I didn't really need--only the driver for my Logitec mouse, in this case.
5) Even doing all this, 10.4.0 was a little flaky for me, but as of 10.4.1 it worked pretty well, and 10.4.2 has been very solid--better than any version of 10.3. As always, I used the "combo" 10.4.2 updater for that install.
Note that I'm not usually this careful--I had done a straight "upgrade" install through every versioni of OSX from 10.0 through 10.3, including mirroring the same install when upgrading from a G4 to a G5, and although this had worked ok, apparently as a result a background process had a tendancy to get stuck and eat an entire processor on my G5 under 10.3, so I decided to go all out and start fresh with Tiger. It took four days (less than the week I'd estimated) before everything was working comfortably again, but it was probably worth the hassle.
Currently at 20 days with 10.4.2, and that includes a bunch of video editing, DVD mastering and burning, two simultaneous users, sleeping frequently, and a lot of oddball stuff on the side. Also, I'm not an uptime fanatic at home, I just haven't had a reason to restart in that long.
