Yes, that sounds exactly like what I am seeing.  The magnification is
symmetric, but there is whitespace between 'pixels'.

Yes, I'm using Xsun from the x11r6 p11 archives that Gordon Ross compiled,
and currently reside on ftp.warped.com, and Xsun does look as though it's
using cg4 just fine.  I'm testing (or will be testing, once the compile
finishes!) removing bwtwo from the kernel, and moving cgfour to it's
address (ff000000), to see if that provides any different results.
