data fault in pci_child_register() for uhci0

[Daniele Forsi <dforsi%gmail.com@localhost>]

I have an USB 2.0 PCI card that is working correctly in an x86 Linux
box but halts the boot of NetBSD 5.0.1 on sparc64 on an Ultra 5 (not
tested on i386). This is 100% reproducible.

Should I send a pr? What information is needed?

This is a copy of the serial console output:
