2.6.25 -- long standing bug with usb after resume with 4GB ram

[Pavel Machek]

Hi!

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.
