I'm talking about the uio_pci_generic module, not about UIO in general.

I know and I really don't have a problem with UIO itself. The
uio_pci_generic module does not export correctly, maybe you take a look
on its code? My guess is, that the uio_pci_generic module isn't commonly
used and therefore the problem wasn't reported before.
