Googleearth works fine...

[nb]

... but still is marked as broken for version >= 90 and architecture amd64.

I tested:

1 - current version from current ports (5.2.1.1588_1,3)
2 - from FreeBSD 8.2 Release ports (6.0.1.2032,1)
3 - from FreeBSD 9.0 Release ports (6.0.3.2197,1)

All three versions work fine on the same machine
(Pentium D, Nvidia graphic card) under both FreeBSD 8.3 i386
and FreeBSD 9.1 RC2 amd64

Maybe combination of nvidia driver, xorg, open GL etc, is sufficient now.
