Ok, At least we know where the issue lies now.  I'll try and look the
code over again, but I behaves almost identically to the kernel routines
I think.  jhb@ wrote us a new ioctl to avoid doing most of this from
userland, but it will be a while before we can count on it's existence
and it doesn't support bios frobbing yet.

Can you verify that pciconf -lvbc does not trigger the issue?
