OBTW, while somebody's looking into NFS and mount, I still (with a
kernel from mid-November) get panics when mounting a CD-ROM with
mountd running. I can try to get a kernel dump with a newer kernel if
anybody's interested.

Speaking of kernel dumps, what happens to physical memory pages when
they're not in use? Are they zeroed? If not, is it possible to add a
kernel option that zeroes out unused pages, or fills them with a fixed
pattern (e.g. f001f001 og deadbeef)? That would make kernel dumps more
compressible...
