 Feedback from qemu developer Aurelien Jarno:
 
 I haven't look in details, but it looks like that the PCI initialization
 hasn't been done. This should be the responsibility of the firmware, but
 the Malta emulation doesn't use any firmware when booting with -kernel.
 It works with the Linux kernel because there is some fixup code which
 does the work if it hasn't been done in the firmware. See:
 
 
 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/a=
 rch/mips/pci/fixup-malta.c
 
 One option would be to implement the same on the NetBSD side. The other
 option is to use YAMON or U-Boot to load the NetBSD kernel.
