    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.
