>Description:

My boot.cfg says:

--8<--
clear=1
timeout=0
load pciverbose
load acpiverbose
menu=:fs cgdrd.img;boot netbsd -vx
-->8--

so I would expect bot pciverbose and acpiverbose to be present in the kernel
after booting.

However, modstat only shows 
[/tmp] master-of-confusion # modstat | fgrep verbose
hdaudioverbose             driver   builtin  -        0       - -
pciverbose                 driver   builtin  -        0       - pci
scsiverbose                misc     builtin  -        0       - -

The bootloader code looks like it creates a list of modules, so I expected
this to work.

The man pages (neither boot(8) nor boot.cfg(5)) explain this case, AFAICT.
