How can I power off ati video card that I have at headless server? Unplugging it is not a solution because mobo has no built-in vga and refuses to boot if vga is not presented.
Is it possible with radeon driver? If not, but it possible with proprietary fglrx, it turns into other question: how to emerge ati-drivers? Emerge stops installation because GPLed kernel incompatible with fglrx (in terms of licence)

Accept the license works with most kernels.

I've found a bit strange solution: I inserted a broken NVidia card into PCI-E slot as a placeholder and started a box. System boots and works fine :D I can communicate with box via ssh, so it is enough for me.
lspci even do not show any video attached, but it doesn't matter for headless server.

There should be an option in the BIOS for ignoring the fact that there is no video card attached.
On mine I just set it to ignore VGA errors :)

That said, I do miss my old textmode AWARD BIOS' with the 9 bazillion options.

These new graphical EFI BIOS' really suck balls (I'mn looking at you MSI and ASUS!), full of stupid bloaty crap and no useful options unless you're really heavily into overclocking! (But nothing if you want to underclock/volt!)

There was stuff you could send powerdown signals to for monitors, I expect there is a similar thing for card? Most cards run in a low power mode unless their 3D engines are activated anyway.

My mobo's BIOS has no such option, I can only select which video I wish to use as primary: onboard or PCI-E.

Yeah, I saw some suggestions on google, like
Code:
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch

but I have no such a slot.
