I have trouble with the 3COM Cardbus bluetooth card on a Powerbook Titanium (a powerpc notebook). I patched the 2.4.20 kernel with the mh-6 patch (and the benh patch which does not collide). I haven't found any hint on the list yet....quoted
You're using a Powerbook and the 3Com is currently not supported on the PowerPC architecture. The Kernel side of the driver should work fine (not tested), but the bluefw have no code to load the firmware. Take a look at the mailing list archive for this problem..../...
Hrm... The problem isn't simple. You are just not supposed to tap IOs that way from userland, especially since PPC arch doesn't have anything like "PIO" instructions. The IO space of your card is actually mapped somewhere in physical memory, that "somewhere" not beeing generally available to userland. Can you tell me more about the card ? Is it a 16 bits PCMCIA device or is it a cardbus (PCI) one ? Why can't you tap the IOs solely from within a kernel driver ?
