ACPI patched kernel and USB mouse problem

[Neville Lee <neville lee polyu edu hk>]

Hello, there,
	I'm using a Compaq Presario 2810AP laptop. After I recompiled my kernel 
with ACPI kernel patch and DSDT patch from acpi.sf.net, the USB mouse 
refused to work while my USB webcam is still working. The light sensor 
in the mouse is on indicating that it's powered. It seems no problm with 
dmesg either. The mouse is recognized by the kernel.
	The only difference, however, is the module layout. With the stock 
kernel from Red Hat's RPM, the lsmod outputs like this:
...
keybdev                 2944   0  (unused)
mousedev                5492   1
hid                    22148   0  (unused)
input                   5856   0  [keybdev mousedev hid]
ehci-hcd               19976   0  (unused)
usb-ohci               21480   0  (unused)
usbcore                78816   1  [ov511 printer hid ehci-hcd usb-ohci]
...
	In the kernels I compiled the output is like this:
...
keybdev                 2944   0  (unused)
mousedev                5492   1
hid                    22148   0  (unused)
input                   5856   0  [keybdev mousedev]
ehci-hcd               19976   0  (unused)
usb-ohci               21480   0  (unused)
usbcore                78816   1  [ov511 printer hid ehci-hcd usb-ohci]
...
	Can anyone explain the lines begin with "input" and suggest a solution? 
I've tried 2.4.20-9 source from Red Hat and 2.4.20 vanilla source. Both 
have such problem. The config file was copied from the original default 
kernel that worked well with the only modification of using ACPI instead 
of APM.
