10.4.3 released; thrill-seekers only for now

I'm one for two with Apple's new 10.4.3 release; it installed without incident on my 12" PowerBook (867 mHz), but rebooted to a kernel panic on the Dual-2.5 gHz Power Mac G5.

I removed all my external devices, ethernet included, and rebooted, still to be greeted by the kernel panic screen. Booting in verbose mode (command-v at startup) showed me a failed dependency when loading the Kensington MouseWorks software, so I came back in safe boot (shift key at startup), ran the MouseWorks uninstaller (by the way, I initially had version 2.6, but upgraded to 2.8 during a brief period of stability, and got the kernel panics back), and rebooted, and, voila, all is back to normal.

It's possible that the real culprit was some interplay between MouseWorks and MouseZoom, which I use to overclock my cursor zooming, but now that MouseWorks is uninstalled, I find that all I'm giving up is custom application settings -- the standard keyboard/mouse drivers do a more than passable job driving my PilotMouse Optical Wireless (bought by mistake: I HATE wireless mice).
