Without knowing anything about hardware, how hard would it be for these guys
to stick jumpers on such things really? I'm figuring they're greedy and
that's why they keep releasing "plug and pray" devices.

I've also seen cards that always think they're the "better" card. For
instance, if I put in an S3 card that supports this, and a Cirrus card that
supports this, they both try to disable each other. Then they either both
stop listening, or one of them does something like "You're a Cirrus. You're
crap. I'm an S3. I rule. Thank you and please drive through." I ran into
this problem with two cheap Cirrus cards the last time I tried to run
multiheaded.
This is unrelated, but while I'm posting to a large community, does anyone
happen to know the vertical and horizontal sync rates for a U.S. Logic
DL-1564M (Cat no. 32-10337)? I don't have a manual for this thing, can't
find it in the Hercules monitor database (http://www.hercules.com), nor can
I seem to find U.S. Logic. I figure the U.S. Logic is a generic of a monitor
that goes under a brand name, but I've no clue what it is.
The monitor is capable of 1280x1024 at 16bpp in Winblows. NT let me select
vertical sync rates up to about 76 Hz. X11 doesn't like those values. I did
get it to display at 16bpp on 1280x1024 a few times, but the sync rates were
obviously -very- retarded. Any ideas?
