Conclusion: no 3ware 9000-series HBA (tw_cl_ctlr_supported IDs) and no Intel i915
GPU (display is Bochs 0x1234:0x1111). Neither sys/dev/raid/twa/tw_cl_init.c nor
sys/dev/drm/i915/dvo_ns2501.c can be exercised at runtime on this guest; PoC
verification for hardware-bound findings in these files is impossible here.
