If you are using the nell pcmcia bridge, please update your kernel config
file (note: this is for sparc nell users only, the sparc64 equivalent will
happen shortly, but SUN4U users are not affected yet).

The WI_AT_BIGENDIAN_HACK option is now obsolete, please remove it.
Instead the nell driver will insist on the presence of the new

options FULL_SPARC_BUS_SPACE

This makes the bus_space implementation complete, thanks to Mathew Green.
At this stage now nell should work with all pcmcia cards support by any
properly written MI netbsd driver. If you encounter any that does not
work, please send-pr.

In the few benchmarks Matthew and I did there was no real measurable 
performance hit by enabling FULL_SPARC_BUS_SPACE, but kernel size increases
by more than 30 kByte (haven't tested the difference on a full blown GENERIC
kernel yet).

That's why it's optional and disabled by default.
