Now a clue of serious breakage.

With mainboard video alone; Radeon card not installed.

~# xrandr -q --verbose
Can't open display

X can't find graphical video. Ouch!

Also noted. With Radeon installed, the BIOS appears to allow choosing
the mainboard video but the selection fails to stick. After reboot the
Radeon card is selected again.

Regarding kernel gfxmode and gfxpayload.

I failed to explain properly. Should have said behaviour is the same
with and without "set gfxmode"; and the same with and without "set
gfxpayload".

I should fix mainboard video before the Radeon addition.

Appears the BIOS update image is not available from a server now.
Might look for a BIOS reset jumper on the mainboard. Tomorrow or
later.

Other ideas welcome of course.

Thanks!                          ... P.
