I have a Latitude CPx500, 2.2r2, and a XIRCOM RBEM56G-100. I had to turn on SHARE_IRQ to get the XIRCOM card working. From /usr/src/linux/.config: # # Character devices # CONFIG_VT=y CONFIG_VT_CONSOLE=y CONFIG_SERIAL=y # CONFIG_SERIAL_CONSOLE is not set CONFIG_SERIAL_EXTENDED=y # CONFIG_SERIAL_MANY_PORTS is not set CONFIG_SERIAL_SHARE_IRQ=y # CONFIG_SERIAL_DETECT_IRQ is not set # CONFIG_SERIAL_MULTIPORT is not set # CONFIG_HUB6 is not set # CONFIG_SERIAL_NONSTANDARD is not set CONFIG_UNIX98_PTYS=y CONFIG_UNIX98_PTY_COUNT=256 CONFIG_PRINTER=m CONFIG_PRINTER_READBACK=y CONFIG_MOUSE=y I also have to force the ethernet card into promiscuous mode to get it working.
