I'm not sure. It looks like hotplug is being obsoleted
Unfortunately, modprobe only decides which module to load. As far as I
know, it doesn't tell the driver which devices to use.
OK, I'll write to the list myself.

It's still not quite good in case of 99 modules :-)

Because it's more universal. I can have an Orinoco pcmcia card and a
Prism PCI card and have them both supported by one driver.
Not having orinoco_pci would be like an artificial limitation for users
with Prism PCI cards.
orinoco_pci is good for testing Orinoco backend on embedded systems that
only support MiniPCI.
Development of the orinoco driver is still going on. Not having
orinoco_pci would limit developers and testers to systems with PCMCIA
bridges (including PLX).
