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
