I don't claim to be an expert on wd.c but from what I can tell it seems that controller and drive capabilities are probed separately, its conceivable you've hit upon an untested code path. ide_pci.c has been changing a lot lately (probably four times in the last seven days) - after capturing your dmesg output, try a fresh kernel and look for differences in probed controller/drive capabilities...
