I'll give this card a few more tries...these things are too expensive

So, it breaks today. If we fix things in the 2.5 kernel, we can clean
up kernel + user-space in the next year or so. We should be able to
write tools that are backwards compatible.
Sure, it sucks to change the interface, but it is just as bad to have
to hack around the byte-packing issues on every new platform/compiler.
