This bug is still present in the latest oneiric (backported to lts version) kernel 3.0.0-13-generic #22~lucid1-Ubuntu.
Worked with some of the maverick kernels, others showed a black box on screen. In the latest 3.0.0 kernel, I get a black screen (even in other consoles).
As described in another post above, sleeping then resuming restores the screen even after hibernating has botched it up.
