It *should* work fine.  I do use it every day.  You might want to just
tar xzpf the files rather than use the install, that I haven't tried.

Maybe.  The 1.6.2 color X server takes about 2.5 meg while running.
The B&W server is a bit smaller.  I faintly remember that the version
from 2.0 required something less than twice that.  That would have
been ok except I don't have enough disk to have enough swap for that
to work.

A little of both.  gcc takes the -msoft-float flag just fine right
now.  The patches have nothing to do what that.  When you give gcc the
-msoft-float flag instead of generating F instructions it generates
CALLs to subroutines which do the FP work.  The catch is, by default,
these subroutines don't exist in libc and therefore the program won't
link.  90% of the softfloat patch is to add these extra subroutines to
libc, the rest is of the patch is things for libm (some of the 040
specific part of the makefiles have 040 specific assembly code).  and
small makefile changes.

Once you have the base libraries (libc and libm probably) built with
-msoft-float then X should build just fine as long as you also make
sure that -msoft-float is used.

When I built 1.6.2's X packages and 2.0beta's X packages I did nothing
special from the soft-float point of view.

The 1.6.2 ones were built by nfs mouting a big disk on my powerbook,
untaring the X src package, and following the build instructions.  If
I started it by about 20:00 it was done the next day by about 9:00
(33mhz LC040).

So, the summary is that you should be able to just go ahead and build
the 2.0 X src, though you will need much disk and time :-(

good luck!

cheers
