slide(4) needs testing on a machine with a PCI_PRODUCT_WINBOND_W83C553F_0. sl82c105_chip_map overwrites the attach args of the IDE controller with attach args of the PCI_PRODUCT_WINBOND_W83C553F_0, I can't imagine this is intentional. However it might not cause obvious problems.IIRC: Symphony Labs was absorbed into Winbond, and the 82C105 more or less became the 83C553.AFAIK there must be some prep boards which came with a 83C553 IDE controller. Also the sandpoint evaluation board X2/X3 got one.
slide(4) has PCI ID 10ad.0105. Here is the DINK32 output from Moto
Sandpoint eval which equips WD83C533;
