The pciephy on rs780/rs880 boards (used for secondary digital outputs)
can only be programmed using the IO BAR (not MMIO).  At the moment, it
only works with kms and requires this patch:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=351a52a2414d2b104269755c86b476863c248034
which is upstream as of 2.6.36.
