Yes, it is. 2.6.21 was OK, but only within a narrow and ill-characterized set of conditions (framebuffer not compiled into the kernel, in particular.) It appears to me that the interaction between STR and video on this system is extremely fragile, to the point that any minor perturbations in the state can break it, and that that is the real underlying problem here.
