drm and intel gm45



Hi,
   having finally got the latest (pkgsrc) X server working on my laptop I 
thought I'd try to get drm working. Built a 5.0_STABLE kernel with i915drm 
enabled and booted but the X server died.

dmesg gives

i915drm0 at vga1error: [drm:pid0:drm_attach] *ERROR* pci_mapreg info for 36

Any suggestions on whats broken? How to fix?

cheers
