Subject: [PATCH] Add support for a boot argument podule?=mmmmpppp to enable
 the manufacturer and product IDs for a podule to be overriden. The IDs are
 specified in hex. A value of "ffff" means disable and replaces the
 podule?.disable option. This allows podules whose IDs have been changed e.g.
 by PowerROMs to still have the correct driver attached. Based on my original
 patch but tided up and debugged by Stephen Hobbs.
