How likely is an OOPS to just have the useful instruction dump but no
other info?
I think the likelihood is in the same ballpark as the likelihood of
vboxdrv being loaded but OOPS being caused by something else.

In both cases we end up losing a OOPS or two - not a big deal IMHO.

Generally the tainted flag is followed by module list, followed by the
IP, Regs, stack trace and then instruction dump.
I would think that if it got around to printing the instruction dump
it would have already printed the module list which is enough for user
space tool to opt out.
