The issue is that on machines where floppy is physically unit 1 and not 0,
the hardware floppy unit swap does not unfortunately work. So, we either can
go and write ugly hacks in generic floppy driver, so that those two will be
software swapped, or we can live with that. And I think the latter does not
hurt that much, especially when the kernel during bootup tells you your
floppy is fd1 or fd0. If you have a PC, you can likewise have a B: floppy
only and not have A:...

Are these numbers # of objects painted per second or time to paint one in
some fraction of time? Concerning text acceleration, I do my best and don't
know how to make it faster a lot (of course, it can be tuned a little bit).
The only 2D things I'm aware is:
	polygons
	bitblt in the same image overlapping to the right
	multiple plane groups (ie. e.g. 8bit and 24bit windows on the same
			       display)

It would be more interesting to see x11perf output on the same box running
Linux XFree86 and Solaris Xsun24, so that we see weak spots in sw
implementation, not hw differences.
