And that helped--in a sense. It produced a kernel that would at least boot
partially instead of a kernel panic, but the boot froze on the distro splash
screen. It's progress, though! I edited grub.cfg (I've read not to do this,=
 but
it was a temporary modification to test a theory) to use "nosplash&quo=
t; instead of
"splash" on the kernel command lin grub entry for the kernel I'd =
compiled, and
once I booted that kernal again, I noticied a 'could not locate modules:
template  usr/lib/modules/$KERNELVERSION" type of error. Again, no way=
 to
screenshot it as it was early in the boot process.

I'm guessing now I've discovered the problem: Renaming the
/usr/lib/modules/$KERNELVERSION directory to something different than what =
the
"make modules_install" command named it when it built the directo=
ry--and prior
to running the mkinitcpio command to build the initial ramdisk--is a bad id=
ea.
Live and learn.

I'm back on track now, and with any luck and free time between day job and
sleep, eventually I'll have a bootable kernel compiled soon so I can actual=
ly
start bisecting to locate the bad commit.
