I built my own boot floppies with your hack, and with the correct things done to the generic kernel conf file (took out pccard stuff, added your device, changed the pci id's to detect both my ti1225, and my fe575c, based on the id's in the netbsd drivers) > pciconf -r pci0:X:Y 0x10 > pciconf -r pci0:X:Y 0x14 > pciconf -r pci0:X:Y 0x18 > pciconf -w pci0:X:Y 0x10 0xffffffff > pciconf -r pci0:X:Y 0x10 > > substitute the correct device numbers for X and Y - you can find that on > the kernel bootup output when it says something like: > > pccbbhack0: <Blah blah> mem blah-blah irq blah on at device X.Y pci0 > > When it boots up and gives the above messege .. it says pccbb: Could not map register memory under your above messege, and doesn't have anything for "mem" but only for irq and device. That is really all I can tell you until I either get a 4.1 CD burnt by someone, or hack the driver enough to make it work :-) (I don't think I can hack the driver, maybe I gave you enough info?)
