Ehci driver(drivers/usb/host/ehci-hub.c), which kernel verison is
2.6.27.1, will export these sysfs.
I don't verify another version.
FATAL: Module r8187 not found.
r8187 is wifi module name.
it may be r8187b in your system.

The sys path is created by sentelic.c (touchpad driver)
Throught it,we can control the touchpad, such as speed, enable or disable.
The standard kernel may be not export these sysfile.
Attachment is the patch about it.
down: error fetching interface information: Device not found
up: error fetching interface information: Device not found
/usr/lib/pm-utils/sleep.d/99yeelong: line 73: echo: write error: Invalid
argument
I'am sorry,it's my fault.
I have mailed an patch to fix it.
Thanks for karl's work.
