You're using the RedHat 2.2 backport which makes unfortunate assumption
about the I/O port range for USB. This causes problems with many systems
as the allocated I/O port range is relatively compact, causing conflicts
like this.
Just add something like this after the headers in uhci.c:
#ifdef pci_resource_len()
#undef pci_resource_len()
#define pci_resource_len(dev, i) 32
#endif
