[PATCH 3/7] radeontool: handle r128 again

[Jonathan Nieder]

An r128 has a tiny (16 KiB) control region and a small (64 MiB)
framebuffer, but radeontool can handle it anyway.

In particular, this gets 'radeontool light off' (and 'on'), which is
often used to work around bugs in Dell suspend support, working again
for the r128.  It hasn’t been working since the change to use
libpciaccess.
