Could the lack of wscons to manage the sparc graphics devices be triggering the kind of unserialized register setting that der Mouse described as a possible cause of this effect?Not directly, because that means that the kernel isn't scribbling on the framebuffer to draw console text; rather, it's punting to the PROM output routines. At least, unless RASTERCONSOLE still exists and you're using it.
RASTERCONSOLE is what's set up in GENERIC for NetBSD/sparc 5.0. Perhaps the next step is shutting that off, and seeing if the problem persists.
