Correct. The Harddrives won't wake up with current kernels. Also, the
DVD drive won't work (or: only in compatibility mode, i.e. no DMA).
Experimental patches for both problems are available, but they won't be
in mainline up to and including 2.6.13. Appearantly, it's not a priority
to the kernel developers.
