Well, I've spent a fair amount of time trying to figure this out, and
I'm glad to say that while I'm not exactly sure why this patch was
causing the failure, it was not this patch. I discovered that other
patches would also cause the esp driver to stop working, which was
baffling.

Eventually, I discovered the failure was the kernel configuration
options I'd chosen. When I altered the sparc32 kernel config options to
closer match those of my working sparc64 kernel config, everything
started working properly.

I've tested this patch on the SS4 with my new configuration, and it
works great. So, take this one off the back-burner and feel free to
apply. :)

Sorry for the confusion.
