Did you completely remove the compile directory for you kernel before
doing the config?

I have done the same as you on a current-ish 10 and I did not get the
duplicate symbols.

I also have no joy, for a start my i915 adaptor id is not in the pciid
list.  I added it with a faked name string but now I get a kernel panic
because the size of the BAR mapping is 0.

I tracked this down to the function drm_alloc_resource in drm_bufs.c
which has, basically, an ifdef NetBSD that contains "This space _not_
intentionally left blank", the function drops out with a 0 return which
means the size of the PCI mapping is 0 and, hence, the kernel panic.

I am not really experienced in the PCI mechanics but I was thinking of
copying the code from elsewhere that checks the sizes of all the BARs of
memory type and returning that sum.  Is that right? anyone?
