I sort of remember there being some tweak/quirks added to the Linux USB     
code lately to work with some of the later Nokia kit, I remember seeing
similar errors too, and figured "oh, they botched up USB in the E70, what
a surprise".

Trying now again with a later kernel ( 2.6.19-1.2895.fc6 ) and newer
software on the E70 (2.x) it doesn't do those things anymore. Doesn't seem 
to work either tho, but at least it doesn't oops:

usb 2-1: new full speed USB device using uhci_hcd and address 2
usb 2-1: device descriptor read/64, error -71
usb 2-1: device descriptor read/64, error -71
usb 2-1: new full speed USB device using uhci_hcd and address 3
usb 2-1: device descriptor read/64, error -71
usb 2-1: device descriptor read/64, error -71
usb 2-1: new full speed USB device using uhci_hcd and address 4
usb 2-1: device not accepting address 4, error -71
 
(trying all the 3 different modes the phone lets you choose when plugging it
in). Oh well. Bluetooth fortunately works well enough.

Some clues:

Maybe N80 is "unusual" too ;) Anyway try the latest FC6 update kernel.
