I fail to understand your point. If a monitor isn't a laptop panel or
some other display which has information in the BIOS tables, and doesn't
do DDC ... what would you like xresprobe to do?

xresprobe is perfectly portable. ddcprobe is not, although that's
fixable (by making it a wrapper around external programs; the one that
reads the EDID out of /proc on powerpc is already there, but the version
of vbetool which uses x86emu needs to grow DDC functionality, which is
trivial, and then ddcprobe needs to be rejigged to support same).

No, they won't need to be supported by xresprobe; you misunderstand its
xresprobe is an external program called by the xserver-xorg postinst,
which is able to seed the xserver-xorg debconf values. Which means
that, if it's successful, then you don't need to bother asking
questions. If not, then you just walk the same code paths as always.
So, there's a potential *huge* net gain. And no net loss.
