Dunno, who good/bad it is, but there has been a patch in comp.windows.x
in the early days of X.V11R4. I haven't actually tested it, as we don't have
suns with GX here, but maybe it's useful for some of you out there!

It's rather short, so I included the whole thing after the sig.
(No flames please!)

Unfortunately R4 does not support the GX. Until Sun will adapt
Xsun to there hardware (hopefully!) I use following little 'quick
and dirty' patch. It accelerates only simple bitblock moves within the
screen, but is very useful in xterm-scrolling and opaque-moves.
