The only major thing that did not work out of the box under Debian was the broadcom wireless (bolded above). It can be made to work minimally with the ndiswrapper driver. I have not tested ACPI fully, but the power button does, actually, initiate a shutdown if you have the acpid running.

Some tweaking was needed to get the widescreen working under X11. I just had to set:

        HorizSync       28-110
        VertRefresh     43-90
and add the "1680x1050" Display mode:
        SubSection "Display"
                Depth           24
                Modes           "1680x1050" "1280x1024" "1024x768" "800x600" "640x480"
Sorry for only the rough notes, I'll post more as time goes on (hopefully). I'm probably going to see if I can return the BMC4309 in favor of an orinoco or intel chipset.
