Alan,
I've applied your patch to 2.6.17-rc4 and it reported no problems. CPU
percentage in "hi" according to "top" indeed decreases, albeit only from
max. 40-something % to 30-something %. There apparently is something in
the driver in combination with the via chip that causes this.

Actually, I haven't found in the "top" documentation nor anywhere else,
what "hi" precisely means. I assume that the CPU is either polling or
forbids interrupts. So, maybe it's a question of locking in the kernel?

But I'm most certainly talking rubbish here since I have not a clue
about the internal workings of the usb driver let alone the kernel.
