An updated source package is up at

By stable, I mean the R 1.9.x series. I don't know if there will be a 1.9.2, but even if there is, I think it would be inappropriate to make changes that could potentially break currently working code. While that's extremely unlikely to happen with these changes, it's possible, and I can't really assume that no one would be affected. For example, it would be possible to get different rotations in different panels using the current lattice (in a non-S-compatible way), by using the 'rot.mat' argument in panel.wireframe instead of 'screen', and that code would no longer work after the changes.

On the other hand, such changes would be acceptable for a major upgrade. The next one's going to be 2.0.0, sometime around October. Till then, you can get the updated version of lattice with the pre-release unstable builds, but not with the 'released' 1.9.x versions.
