     IIRC amd64 was loading lkms into the ISA I/O hole and so corrupting 
shadowed
     ROM images, video memory, etc.
 
 DEV       0  -1/161 ffffffff80e24000 00b4 ffffffff80e4c820   2 pf
 
 this doesn't seem anywhere near ISA or VGA memory?

     I have a patch to disable /dev/ksyms usage in modload. It doesn't really
     matter for the LKMs that we ship.
 
 i thought this used to work.
 
 i haven't gotten around to testing a netbsd-4 system to see what
 happens there yet though.
