I tested Puppy Wary 5.2 - it works fine. It detects the video card but not
the monitor, so I select from a list: 1024x768x16 h31.5-49,5v56-72. This
works, fills the entire screen. I don't know if it is the maximum
resolution, the documentation does not say (only that is TFT 14"??? (N618)
or 15" (N619-N620) XGA.

IIRC, 5.2's 2.6.33 was the last kernel version without having KMS built in by default. Given why that distro exists, it's pretty safe to assume it had no KMS.

I suppose so.

Therefore, comparing its video behavior to anything newer is little more than a does it work or doesn't it exercise, with nothing to be learned regarding getting anything newer working properly.

It shows that the hardware is capable :-)
If it worked with older linux software, it should also work with recent software.

Without KMS (e.g. in conjuction with nomodeset, or using pre-2.6.34 kernels), vga= works as it always had. With KMS, for what vga= did for framebuffer ttys previously, one needs video= instead. Compare the two's descriptions in kernel-parameters.txt.

But "video" does not work, and "vga" does. And lsmod shows that drm, i915, drm_kms_helper, are loaded. Xorg log says kms is in use. I don't have 'nomodeset' as boot parameter.

The display runs at 1024x768x60, I think.
