It turns out the kldload command itself have no output. all output are from dmesg.
What can I / should I do?
Interesting section of 'pciconf -lv':

By the way I tried to compile a kernel without ppc driver, thinking it causing trouble. Result is:
tobago# kldload snd_driver
driver bug: Unable to set devclass (devname: (null))
driver bug: Unable to set devclass (devname: (null))
driver bug: Unable to set devclass (devname: (null))
