Well, as I understand, both options are not working on the 9.2 driver.

This is how I've understood it, too. At some point the first solution stopped working (might have been around 8.12~ish) and then the latter solution stopped working. In addition, the latter solution always hung up peoples boxes at the next X.org sartup, so people needed to use some script to delete the amdpcsdb.

Yeah, this sucks.
Now it has become very bad on my install: I am no longer able to use the 9.2 catalyst, X server produces a seg fault at start up.
With ati driver, at X startup, 50% of the time the Samsumg TV indicates a "not supported mode". I have to switch from terminal mode to X mode (Ctl+Alt+F2 / Alt+F1) many times until eventually I get the TV displays the Gnome desktop (or until I am tired) !
It is really depressing to have reached such a usefulness state after so many efforts...
Will CC 9.3 version be our saver ?
You probably need to remove your /etc/ati/amdpcsdb file. If I use amdcccle at some point it (or driver or whatever) saves current resolution there just to set it again when X is restarted. For some unknown reason that causes crash on startup.
By removing the whole file or just needed lines in the file you can probably start it again.
At last I can insert happy face to the title
New 9.3 release actually fixes overscan perfectly. It also seems to have as good performance as 9.2. So good work ATI!
The issue mentioned in previous message (crash on startup if amdpcsdb contains resolution set on startup) is still available, but if this driver is as stable as previous I don't care for now. I rebooted this computer about twice when 9.2 was used (and neither of boots was caused by ATI drivers).
In 9.3 Catalyst Centre there is a setting (slider) for adjusting the underscanning that when put to 0% fixes the problem. However next time X will start it will crash (fix is to restore /etc/ati/amdpcsdb file to the default before starting X).

Using 9.3 and the Control panel to set underscan to 0% does not crash X for me. Work perfectly. It is about time ATI fixed that issue.

I confirm that X start up crashes at the nex start-up unless I reset the default values.

Please, if at least I could issue an aticonfig command to restore my parameters automatically when Gnome session is opened, that would be nice (rather than going manually into CCC each time)
I just picked up my new Nvidia GeForce 9400 GT. Not ATI for me for a while...
