[Nut-upsdev] usbhid-ups causing hang on boot with 2.6.35 - any ideas?

(Arjen - I apologize if you get two copies, I sent the first one to the old 
de-korte.org address)

Arjen, all,

	I've run into a usbhid-ups problem with nut on Arch Linux with the new 2.6.35 
kernels. (latest is 2.6.35.4-1) For some reason when you get to the udev events 
on boot and it tries to load the usbhid-ups driver, it hangs until the 120 sec 
timeout occurs and then boot continues but with no usbhid-ups configured. Here 
is the log info:

     Looks like some type of udev issue or kernel issue, but I thought I would 
check here to see if you guys have any more info on the problem. Anybody seen 
this behavior before?

     Seems to effect my MSI nvidia 8200 chipset box more than others. This box 
has never had a problem with this before the 2.6.35 kernels so something has 
changed that impacts the driver, but I'm not sure what it is. Can you think of 
any other tests I could run to help narrow it down?

     Any help would be appreciated - thanks.
