Kernel panic

Hmm, another security update, another new problem. This time, I'm getting a bunch of kernel panics, often on startup. (As an aside, I should point out that I had to look up what the multi-lingual message about restarting the computer was about—in other words, these are the first kernel panics I've had in a year and a half of using Mac OS X day in, day out).

No indication (in /Library/Logs/panic.log) of what the problem might be, but things seems to have stabilized now.

[Edit 4-Nov-06: I now suspect the problem might have been half of the memory failing]
