Yesterday I experienced a run of kernel panics on my 12" PB. After the first panic occurred I was unable to reboot successfully - 4 or 5 successive reboot attempts all resulted in another panic during the reboot.
However, I got afeeling that perhaps there was a problem with memory so I took out the
512Mb RAM module, ran the tests again with a base 128 Mbyte system and
everything passed. Then I re-inserted the 512 Mb memory module, re-ran
the tests, and once again everything was OK. Next step was a boot into
single-user mode to run fsck, which also came up OK - no problems
revealed. Finally a full reboot into normal mode was successful, and
it's been OK since then, with a couple of reboots, and at least one
'wake from sleep'.
It's possible that the ram became loose. I periodically have a problem with
kernel panics when I pick my 12" pb by the left front. Turns out that, over
time and with the jostling that comes of carry it everywhere, the Airport
card comes every so slightly unseated. It's not enough to interfere with the
Airport functions but it causes the panics. So, I take the card out, put it
back and then everything is fine for several months. Could be a similar sort
of thing.

In fact further checking has lead me to thing that the issue may indeed be with the Airport card rather than the RAM module - it has only happened when I was working wirelessly, and checking the panic.log file revealed a reference to a module called 'com.apple.iokit.AppleAirPort2(3.1.2)' .
And indeed I reseated the Airport card last night and it's been OK since then.
Meg, when you say 'it's not enough to interfere with the Airport functions but it causes the panics', what do you mean? Have you ever run the Test CD after a crash?
