Oh, this is an interesing test case :) Native mode is  supposed to work, but
I don't think it has ever been tested.

Well, what you can do is set wdcdebug_atapi_mask, wdcdebug_mask and
wdcdebug_pciide_mask to 0x10 (DEBUG_PROBE). You can do it in the sources and
recompile it, or patch the kernel with gdb:
gdb --write /netbsd
set wdcdebug_atapi_mask=0x10
set wdcdebug_mask=0x10
set wdcdebug_pciide_mask=0x10
quit
