Exactly what in the wlandebug output are you looking for?  I've posted a pic
at http://www.vnode.se/sc/panic_20110906.jpg showing what it looks like right
before the panic.  This is with "wlandebug 0xffffffff".

I've also installed kernels all the way back to revision 222980, but they all
panic, which I think is somewhat odd.
