Those certainly do appear to be fairly uncommon if not rare.
1.) Once installed an the new xorg.conf is generaed, edit the xorg.conf with kwrite or kate. (as root type "kwrite xorg.conf") and repair the xorg.conf BEFORE you reboot. You should make a backup of the original before using fglrxconfig, so it should be easy to tell what needs to be editted in the keyboard layout section of the file. My guess is: during fglrx config there is a section asking for desired keyboard layout, standard is 0 I blieve, which is en/us, perhaps you hit a different key...
2.) That one is very odd... I am gonna ask... how about after a FULL shutdown unplug? I have heard of a couple of strange things upon rebooting wihout shutting down between linux kernels, certain bios enbled onboard nics(settings vary there, sometimes has to be wake-on-lan enabled, others just nic enabled) and windows. You can try bios update, playing with the settings... kernel upgrade to latest(or just install suse 10.1 instead of 10, it is mere weeks away)... otherwise... I don't know for sur about this one. It is indeed rare and odd.
