I didn't look at this closely, but sounds like disabling vgacon on microblaze made sound drivers fail because they or microblaze does not enable something in the kernel config.
Looking at this shortly, the reason is that EXPORT_SYMBOL() of isa_io_base is missing for microblaze. I don't know, though, why the mentioned commit triggers the bug, too...
