How often is this used?

It's arguable that this is a bug in the SCSI and IDE drivers. Users _do_ 
just pull cards out. We should deal with it, not oops and die. This is a 
fundamental part of what hotplugging means, especially to users of 
consumer devices.

Or specific drivers for the PCI drivers need to be provided. The i82365 
driver with all the PCI stuff is a horrible mess. I tried putting back the 
non-CardBus PCI support at one point. It was ugly, and didn't work. 
Someone's now working on a driver for the Intel i82092AA bridge, and I 
think that's the best answer for the other PCI-PCMCIA bridges too, rather 
than merging it back into the ISA i82365 code.

I'm trying to get some time to work on it, yes. 

I was actually coming to the conclusion that I'd prefer just to ditch the
whole of the existing PCMCIA support and rewrite it from scratch as a kind
of hot-pluggable isapnp, which is basically what it is (when you remember
that PCMCIA != CardBus).
