Cool!

why? [..] It looks like bad device numbers

The devices are disabled by LB because of the 0xffff VID.
Theory: Some bit needs to be set somewhere in order to have the IDE PCI device actually exist and return anything meaningful?

..and at this point that bit has been set, but the device hasn't been enabled properly?

You could also try using my FILO IDE patch with the debugging suggested in my message, it may provide some more debugging hints:

printk_err("NO HARD RESET ON VT8237R! FIX ME!\n");
Remove the function and undefine HAVE_HARD_RESET or whatever the option is called then
