I am not sure how to do this.  I did try setting the DRM_MAX_RESOLUTION_* in
in the kernel but I just get a blank screen when drmkms kicks in.  The
machine isn't hung, just no display.

I only have FONTBOLD_8x16 and FONTBOLD_16x32 in my kernel config.

That is good - I am missing X at the moment.

I had a bit of a search for information on i915 and found the Intel
doco.  One of them is a document that has about 40 pages of errata work
arounds which is downright scary.  I know that the NetBSD driver does
apply work arounds as part of the code but I am wondering if there is
one that has slipped through the cracks, there do seem to be quite
a few work arounds for gpu hangs.
