Hrmm.. Interesting, yes, you're probably right! In fact, I found the patch
that makes Linux force the IDE controllers on in the LinuxBIOS -> kernel
configuration. I forgot about that and assumed RedBoot would just work
because the Linux kernel just worked. Alright, I'll get something in and
working real soon, and if there's a good generic way to do so on all x86s,
maybe it'd be worth it to fill in that HAL_IDE_INIT macro.
Thanks again, you probably just saved me days :)
