panic! panic! panic! sigh.. panic!

[Ephaeton%gmx.net@localhost]

So I've got this IBM T61 laptop, added a 2 gig piece of ram and thought I'd 
enjoy
it with some massive package building.. then it hung (while in X). So I 
rebooted,
found my X (from pkgsrc) was gone in the update process and continued package 
building.
The next panic thus I could take a photo of, even do a bt. It was happening in 
some
invocation of as(1). So I rebooted again, finished building of my X packages, 
including
the windowmanager and started xdm. Bazong... you guess right. The next panic.

Hmm, any hint what it could be related to? Any hint on what I should do next? 
Which
DEBUG stuff do you advise me to turn on? What does it smell like??

Oh. Just while I was writing this the machine hangs again. This time the thing
trickling it seems to be xmms, which wants to read a new song from the disk 
while
in the background a pkgsrc build is running.

bt1 (just the end of it) can be seen at
 http://ayaken.net/bt1.jpg

bt2 (2 parts) at
 http://ayaken.net/bt2-1.jpg
 http://ayaken.net/bt2-2.jpg

I don't have a bt of the 1st or 4th crash now.

TIA. -Martin

(PS and I'm not PRing because what should the subject be? NetBSD doesn't like 
me?)

machine kernel conf:

Differences to GENERIC: A lot of stuff has been commented out. The
additions are the DRM stuff from ALL, uncommenting the aps entry,
adding file-system PUFFS and pseudo-device putter (for PUFFS), and
-makeoptions    CPUFLAGS="-march=i486 -mtune=pentiumpro" # Assume at least 486, 
...
+makeoptions    CPUFLAGS="-march=pentium4 -msse2 -mfpmath=sse" 

The disks are mounted with -o log in the meantime, the crashing started
without log though. It hung even before I've added the 2 GB of RAM. So
I suspect that's unrelated.
