I have already adopted that patch independently,
and it has done wonders for stability with 2.6.14-rc4
coming back from suspend-to-ram.  Or is that just my imagination?

But I have not yet tried reenabling CONFIG_USB_SUSPEND in conjunction
with that patch -- just too much grief and wasted time every round
I try with CONFIG_USB_SUSPEND.  I'll get to it again eventually though.

Cheers
