So Kenji is arguing that _STA should be called before _SUN (iow that the _SUN
value is bogus unless _STA indicates that the slot is powered)? That seems
harder for the user; often times you want to find a slot even if it's powered
down & empty (say to add a new card)... It looks like the current code won't
provide a slot name on Fujitsu machines in this case, or am I missing
something?
Thanks,
Jesse
