First of all I tried to run the upgrade process but it's a bit more bloated so my 4GB root partition started to look really tight. I had to move stuff around to make room for some of the bigger updates to install and although they all fit it was rather tight so I repartitioned with 6GB. Feeling brave I went for KDE 4.1 rather than KDE 3.5 and Compiz.
The install was more painless than 11.0 but not without a few caveats...
The Atheros card works fine with the Ath5K driver now - however, we now have the stupidity of the generic 80211 drivers which defaults to the US regulatory domain. I have configured the system with UK English, the firmware on the card says EU regulatory domain - figure it out guys. Ironically, the original madwifi drivers could figure this out. The fix is to create /etc/modprobe.d/cfg80211 which contains:
options cfg80211 ieee80211_regdom="EU"Video configuration was better, 1024x600 could be configured out of the box without problems. The font scaling this time seemed to be a bit small, so I opted to claim that the screen was 13.3-inches 16x9 to get a good font size.
I had to eradicate both beagle (by uninstalling everything in Yast containing "beagle") and nepomuk (from the KDE menu select Personal Settings|Advanced|Nepomuk) to stop the background flash and performance maiming chuntering they generate. I also disabled the Update Applet (just configure not to load on login) and a selection of daemons like NFS and CUPS which I'm not going to use.
Other things, like using tmpfs for /tmp and /var/tmp and noatime on ext2 for stuff on flash are as before.
Subjectively, 11.1 seems to be a bit snappier than 11.0 - taking 30 seconds to reach a login prompt from GRUB and another 20 from login to usable desktop.
KDE 4.1 actually doesn't seem to be too bad. Initially it seemed rather slow but that turned out to be nepomuk messing things up in the background. However, I did revert to the "Classic menu" and "Classic desktop" and removed the vile startup and shutdown sounds
