Hmm, type 1 is SYS_RES_IRQ. IRQ resources should not be marked reserved.
Oh, some other child of vgapci has already allocated the IRQ. That seems odd.
Can you get 'devinfo -r' output before you kldload i915kms and again after
doing the kldload? (No need to run startx)
Please note I originally loaded "i915.ko", not "i915kms.ko"
Full output of the devinfo -r attached (no modules, w/i915 and w/i915kms),

Unfortunately, "kldunload i915kms" makes my screen blank
and probably crashes the system (disk activity stops after
a short while and there is no response to the keyboard input).
