    Hi Julian,

    The usb.ko module failed to load with these patches (usb_allocmem
    undefined). Adding usb_mem.c to SRCS in /sys/modules/usb/Makefile seems to
    fix this - my USB mouse, flash reader and cheap-ass 'pen drive' all appear
    to be working as before.

    One strange thing though - booting from my usual kernel (which loads most
    things from modules) I get some extra whining when the USB ports are being
    probed:

    uhci0: <VIA 83C572 USB controller> port 0xd800-0xd81f irq 10 at device 7.2 on pci0
    usb0: <VIA 83C572 USB controller> on uhci0
    usb0: USB revision 1.0
    uhub0: VIA UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
    uhub0: 2 ports with 2 removable, self powered
    uhub0: port error, restarting port 1
    uhub0: port error, giving up port 1
    umass0: Generic Mass Storage Device, rev 1.10/1.00, addr 2
    umass0: Get Max Lun not supported (STALLED)
    uhub0: port error, restarting port 2
    uhub0: port error, giving up port 2
    umass1: DMI MultiFlash, rev 1.10/1.00, addr 3
    uhci1: <VIA 83C572 USB controller> port 0xdc00-0xdc1f irq 10 at device 7.3 on pci0
    usb1: <VIA 83C572 USB controller> on uhci1
    usb1: USB revision 1.0
    uhub1: VIA UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
    uhub1: 2 ports with 2 removable, self powered
    uhub1: port error, restarting port 1
    uhub1: port error, giving up port 1
    ugen0: LEGO Group LEGO USB Tower, rev 1.10/1.00, addr 2
    uhub1: port error, restarting port 2
    uhub1: port error, giving up port 2
    ums0: Logitech USB Receiver, rev 1.10/9.10, addr 3, iclass 3/1
    ums0: 5 buttons and Z dir.

    Booting from a GENERIC built from the same sources, I don't get any of the
    'port error' messages:

    uhci0: <VIA 83C572 USB controller> port 0xd800-0xd81f irq 10 at device 7.2 on pci0
    usb0: <VIA 83C572 USB controller> on uhci0
    usb0: USB revision 1.0
    uhub0: VIA UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
    uhub0: 2 ports with 2 removable, self powered
    umass0: Generic Mass Storage Device, rev 1.10/1.00, addr 2
    umass0: Get Max Lun not supported (STALLED)
    umass1: DMI MultiFlash, rev 1.10/1.00, addr 3
    uhci1: <VIA 83C572 USB controller> port 0xdc00-0xdc1f irq 10 at device 7.3 on pci0
    usb1: <VIA 83C572 USB controller> on uhci1
    usb1: USB revision 1.0
    uhub1: VIA UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
    uhub1: 2 ports with 2 removable, self powered
    ugen0: LEGO Group LEGO USB Tower, rev 1.10/1.00, addr 2
    ums0: Logitech USB Receiver, rev 1.10/9.10, addr 3, iclass 3/1
    ums0: 5 buttons and Z dir.

    This doesn't seems to have any effect on whether things work or not though,
    other than the umass devices coming up on different SCSI busses if I don't
    load USB from the module, but I think that has always been the case.

    Otherwise it looks good.
