googleearth and radeon driver?

[Tom Horsley]

Other 3D apps I've tried seem fairly snappy, and with desktop effects
enabled, my windows wiggle weasonably well (as Elmer Fudd might say),
but googleearth seems agonizingly slow. I see these messages if I
run it from a terminal:

zooty> googleearth
libGL warning: 3D driver claims to not support visual 0x4b
*********************************WARN_ONCE*********************************
File r300_render.c function r300Fallback line 428

Try R300_SPAN_DISABLE_LOCKING env var if this hangs.
*********************************WARN_ONCE*********************************

Mean anything to anyone?
