There are problems with usb after suspend/resume... it works as long as memory is limited to 3G -- probably because iommu/agpgart/something is not used in such case. rmmod/insmod of ehci_hcd & ohci_hcd fixes that. For testing with 2.6.25, you'll need aperture_64.c patch that makes iommu as nosave (or it oopses). Problem is also present in opensuse10.3.
