  /boot/kernel/ contents: ahci.ko ehci.ko hpfs.ko ipfw*.ko ng_*.ko (only
  legacy netgraph, NOT netgraph7) ohci.ko pf.ko radeonkmsfw*.ko sdhci*.ko
  uhci.ko xhci.ko

kldload attempts (all fail, modules not present):
  kldload ng_hci                 -> kldload: can't load ng_hci: No such file or directory
  kldload ng_ubt                 -> kldload: can't load ng_ubt: No such file or directory
  kldload ng_btsocket_hci_raw    -> kldload: can't load ng_btsocket_hci_raw: No such file or directory

Bluetooth hardware: none exposed to the QEMU guest (hw.bwn.bluetooth sysctl
reads 1 but no BT HCI adapter is attached; the bwn driver is for Broadcom
wireless, not Bluetooth).
