There's a more comprehensive fix for this in 2.6, as needed to
support the more generic driver infrastructure for devices
("driver model") that aren't on PCI, and the more generic DMA
infrastructure which likewise doesn't try to make everything
act like PCI. There are also a lot of other improvements in
2.6 for the HCD framework ... some of them might be useful
for such a "virtual HC". (In fact, look at dummy_hcd; that's
also a kind of "virtual HC".)
If this works for you on 2.4, it should be no problem to merge.
