I am aware of the fact, thank you, especially after spent long years
supporting them :)
The issue I want to raise is actually on the "console redirection"
capability. All the Sun's own server, whether it is SPARC or x86, is
having the serial console, whether you get Forth OBP, Service Processor,
ALOM, ILOM, ELOM.
So on the x86 line, user will not get the usual BIOS screen ala Phoenix
and Awards. Thus no video capability is needed. However, the LX50 and
V20z/V40z are not Sun's own design, they are just OEM. Forgot about the
LX50 but it is Tyan motherboard, and V20z/40z are from Newisys. Thus
they are using more traditional PC style console, with VGA controller
embedded on the motherboard like normal PC.

They have, on board. With Dsub15 pin connector on the back.
You can always go to the Sun System Handbook to verify that. Check the
IIRC, the V20z/V40z was using the Trident 3D chipset, thus VESA friendly.
The LX50 IIRC, the Intel GMA, but not really sure, too long to remember.

I am afraid it is the other way around. The Linux for SPARC on the
Debian distro is actually compiled for the UltraSparc II/III/IV(+), the
sun4u family machine.
Whether it is working for the CMT processor (UltraSparc T1/T2(+) or
sun4v machine possibly a show of backward compatibility of the CPU.
However, disclaimer, I never tried the Ubuntu on sun4v machine. My
pocket money can only buy me from eBay the Ultra 1/2 and Ultra 60/80.

Just ensure that there is no keyboard connected to push the console to
the serial port A.
