What is the preferred way of accessing non-PCI devices then? Direct
pointer access?

No direct pointer access is bad. On PPC You can use
in_be{8,16,32}/out_be{8,16,32}

What about arch independent drivers? Are there any generic approach
for this or do you have to stick to ugly #ifdefs to decide between
in_be32/inl ?

ioread*be()/iowrite*be() can be used for this. Since the generic
big endian accessors became a standard thing a little while back,
all the PPC on-chip drivers should move to that. It's just a matter
of time.
