Yup --

I updated those Makefile and files in distrib/i386 that were different
by copying the -current versions into my sup (i.e. releasebranch) based system,
and now boot-big.fs is created with the correct size.

I updated these files (which are probably more than needed):

distrib/i386/floppies/bootfloppy-big/Makefile 1.7->1.8
distrib/i386/floppies/bootfloppy-common/ 1.26->1.28
distrib/i386/floppies/fdset-common/ 1.16->1.20
distrib/i386/floppies/ramdisk/Makefile 1.29->1.30
distrib/i386/floppies/ramdisk/ 1.12->1.13
distrib/i386/floppies/ramdisk-tiny/Makefile 1.1->1.2
distrib/i386/floppies/ramdisk-tiny/ 1.1->1.2

The relevant changes for making the full-sized 2.88MB disk image should be pulled into
the release branch as suggested above :-)

The resulting CD-ROM ended up being mostly bootable, i.e. the PC boots, the boot-loader
executes and loads the kernel, but the PC resets after loading the kernel, but before gets
to writing anything (at least I did not notice anything on the screen). This is repeatable
and it also happened on another PC.

I don't know the reason, and tomorrow, I'll probably try to do a new make release.
I don't even know whether to suspect the CD building or a kernel problem, but note that
this is on a machine which is already running 1.5ALPHA from sup.
