The bug is still reproducible with current r300 driver from mesa git and 2.6.34-rc6 from kernel mainline build. I suspect, however, that this is a mesa bug and not a kernel bug. See also this comment from https://bugs.freedesktop.org/show_bug.cgi?id=27507#c1 :
"0ad problem is that mesa sets wrong height for rendering area (1023 instead 768)."
