The pci_enable_device() in your changeset is not enough, unfortunately.
My Promise Ultra66 (which others, including Andre Hedrick also use)
doesn't identify as an IDE storage controller:

[mlan@piglet ~]$ lspci
00:0b.0 Host bridge: Apple Computer Inc. Bandit PowerPC host bridge (rev 03)
00:0d.0 Unknown mass storage controller: Promise Technology, Inc. 20262
(rev 01)

Would it be possible to select on mass storage in general? If that is an
'official' classification, that is...

Well, we could. That is supposed to remain a temporary hack until we find
a better way to tell the IDE driver to stop avoiding disabled cards if
told so by the arch.
