vesafb is known to have adverse interactions with suspend and/or hibernate
on some systems; and we have no good way to selectively enable it *only* when
the nvidia binary driver is enabled. (Even if a good method to selectively
enable it was identified now, it would be too late to regression-test such a
change for the 10.04 release.)

The vga16fb module, OTOH, is always safe to load, since if a better
framebuffer is available, it won't be used.

Yes, you get VGA resolution, which is 640x480. The committment here was
that we would have a graphical splash with vga16fb, not that it would look
as good as the splash on the other framebuffers. The latter is not
possible.

What are these text messages?

That's the separate bug #540801.
