hi Craig,

say what <g>? "verwechselt" does mean, "taken for someone else". you sure
you eanted to say this? ;)

hmm, dunno how i should handle b), though..

and PCI card at 0:11.0 !!! lspci shows it fine, but *I* see nothing on the
monitor. i fear i expressed myself badly, sorry! the PCI card is simply not
initialized or whatever. pci card
monitorLED keeps flashing. there is no input from the card.

am i correct that you misunderstood me, and thought lspci woudnt see the
card, or should i change slots anyway? dunno what i could get except a
different number, 0:9:0 or whatever? or should the pci card become 1:0:0?
is this the goal? anyway - booting from PCI will not bet me further, i
guess we all agree on this..

well, it is seens, lspci shows it, but there is no data going from the pci
card to the monitor.

i try to summarize this again:

if i connect my AGP only, EVERYTHING is working as expected. no problems
whatsoever.

if i add my PCI card, BOTH are seen. AGP 1:0:0, PCI 0:b:0.
if i boot from AGP, i see the bootprocedure on the AGP, nothing on PCI. then
X starts, i am still on AGP and see nothing on PCI. NOTHING, not in normal,
not in xinerama mode! now i press ALT-F1 to get a tty, and this is NOWHERE.
not on my AGP and neither on my PCI. i press ALT-F7 again, and X is back on
AGP.

now, if i boot from PCI then everything is correct. bootprocedure starts
from PCI. X starts - both monitors. i press ALT-F1 and it is shown on PCI
(sure, i booted rom that card). X remains on AGP. this is fully correct to
me, except that it is an ld card i dislike to use at primary. its a voodoo
banshee, dont even know if it does 1600x1200 if i would keep that as
primary.

well, i hope this gets a bit clearer now?
here some more parts of my xconf (fonts etc.. wiped out so it doesnt get to
much). [0] is my AGP and 19", [1] is my PCI and 17":
