How is it possible to set screen resolution on pi, as vga= in plan9.ini
or cmdline.txt seems not to work and config.txt looks not very Raspbian
compatible?

I just used config.txt last time I had to fiddle with that. Took a few
tries but now it works with my ancient monochrome CRT and a cheap HDMI
adapter.
AFAIK config.txt is only parsed by the Pi's bootloader thingy so I'm not
sure what you mean by it not being compatible. Raspbian will need
different options set, but the syntax is the same. Options related to
HDMI should be the same too.

config.txt is exactly the same format. Look up the pi docs on it; my
screen was incorrectly detected so I had to override detection and
disable overscan, for instance.

OK, thanks guys, was just a bit stupid looking at the files - found a
solution on stackexchange:
disable_overscan=1
hdmi_ignore_edid=0xa50000080
hdmi_force_hotplug=1
config_hdmi_boost=4
hdmi_group=2
hdmi_mode=36
Works on one of the raspberries, but seems I crashed the SD of the
other... will have to order a new one.
