Help with CardBus hotplug on kernel 2.4?

I'm trying to figure out if an Elan Digital Systems P111 CardBus to PCI adapter works with my Mac 8500. I have read that sometimes PCMCIA adapters don't work because of problems with ones motherboard.


As a test I'm trying to use an Adaptec APA1480A CardBus SCSI Host Bus Adapter that I have used successfully with my Slackware Compaq laptop. I am using the 2.4.19-4 (I think) kernel sources with the powerpc patch on a Macintosh 8500 with a G4 PowerLogix CPU upgrade card.

The TI 1211 PCMCIA bridge chip on my Elan is recognized by the kernel when I boot:

Linux PCMCIA Card Services 3.1.33
  kernel build: 2.4.19 unknown
  options:  [pci] [cardbus]
Intel ISA/PCI/CardBus PCIC probe:
PCI: Enabling device 00:0d.0 (0004 -> 0006)
  TI 1211 rev 00 PCI-to-CardBus at slot 00:0d, mem 0x80804000
    host opts [0]: [pci only] [pci irq 23] [lat 32/176] [bus 4/0]
    PCI card interrupts, polling interval = 1000 ms

But I can't seem to get my APA1480A to show up. "cardctl status" says "Socket 0: no card". Removing and reinserting the card doesn't do anything.

I've never used hotplug PCI before. One has a choice when building a kernel and the pcmcia-cs package as to whether or not to use hotplug with the cardbus support built with the kernel or with the pcmcia-cs package. On my compaq I don't use the hotplug support.

I noticed that "make-kpkg --revision pishi.1 modules_image" to build the pcmcia_cs modules didn't build apa1480_cb.o.

I get the impression from reading the hotplug readme that one wants all ones drivers to be modular. But I need the AIC7xxx driver to be non-modular because I boot off an adaptec 29160. Both my adaptec PCI card and my cardbus card need the same driver.

The hotplug readme was very brief and didn't really help me out.
