For the TGA. The Permedia based card would be clear "PC world" issue and
directed to XFree.
Hm. For this lookup logic... don't confuse XdecNetBSD (or XalphaNetBSD) with
XFree86. I'm talking about XFree86, and this doesn't read the rotary switch for
resolution but instead gets the resolution from the first valid mode resulting
from mode scan, and comparing width and height (only these parameters) with the
table of modesfor the switch. Really. It's not very useful :)

As my TFTs don't know about sync-on-green (at least my X-terminal doesn't work
with this), and i didn't configure it in XFree86, i don't think so. But it's a
hint. Anyway i wanted to try with sync-on-green with these monitors, as DDC
mentions it. It seems i have to twiddle something with VSYNC to get
