Hi Troy and Jarek, I have now a FJS S7110 notebook for testing (see lspci -v below). It comes with an Intel Core Duo CPU and ipw3945. I would be really glad to see the ipw3945 working. I could rebuild the kernel ipw3945 module without any problems - many thanks to Jarek! However, on this hardware ipw3945 still does not work. If I load the module, I get the following error: kernel: ipw3945: Intel(R) PRO/Wireless 3945 Network Connection driver for Linux (with 80211 built-in), 1.1.0-pre2 kernel: ipw3945: Copyright(c) 2003-2006 Intel Corporation kernel: ACPI: PCI interrupt 0000:05:00.0[A] -> GSI 18 (level, low) -> IRQ 217 kernel: PCI: Unable to reserve mem region #1:d0100000@30000000 for device 0000:05:00.0 kernel: ipw3945: probe of 0000:05:00.0 failed with error -16 I see the error on the latest SL4 kernel and as well on the latest SLC4 kernel. I also took the latest ipw3945 version (1.1.0) - still the same problem. With a 2.6.17 kernel running under SL4 ipw3945 works just without any problem. The problem seems to be a "memory conflict" between the ipw3945 and the CardBus bridge (?)
