Should I suspect that's still present in grub and is for some reason
problematic under bullseye?  Any tips, hints, suggestions, wild-eyed
speculations would be appreciated. :)

thanks, Christian and Greg. :)   Here's the 'tweak' that has worked well
for years, before this upgrade - I'll break it into a few lines but it's
all one line in /etc/default/grub:

GRUB_CMDLINE_LINUX=
"video=640x400.
consoleblank=600 reboot=pci radeon.cik_support=0 amdgpu.cik_support=1"

Changing video=640x400 to video=640x480 overcomes the "Input not support"
error problem but makes the characters smaller and leaves some screen real
estate unused -- which is exactly why video=60x400 is what I had
eventually added to the command line in the first place. :(

Hardware has remained the same.  What does anyone think has changed in the
upgrade to produce this odd problem?  Is there a DVI module or driver that
would be a likely suspect?
